We’ve all done it—typed "xoxo" at the end of a message to a friend, a lover, or even a coworker when we wanted to soften a request. It feels automatic. Natural. Yet if you stop and think, it’s kind of bizarre: two letters, no vowels, zero literal connection to lips or arms, somehow encoding centuries of emotional shorthand. The real story behind "xoxo" is tangled in medieval religion, Victorian etiquette, and the quiet rebellion of emotional expression in written form. And that’s exactly where we’re diving in.
The Origins of "X" as a Symbol for a Kiss (More Complex Than You’d Think)
The "x" in "xoxo" traces back to the Middle Ages—yes, really—when literacy was rare and signatures were acts of faith. Signing your name with an "x" wasn’t a casual shorthand; it was a sacred gesture. The cross was a symbol of Christ, and placing an "x" on a document was like swearing on a Bible. You’d kiss the "x" to seal the oath, a physical act of devotion that merged body, belief, and contract. That kiss wasn’t romantic. It was ritual. It was binding. And over time, the gesture outlasted its religious context, morphing into a general sign of sincerity.
Fast forward to the 18th and 19th centuries, when letter writing became a refined art among the upper classes. Women, especially, were expected to be emotionally restrained—too much passion on paper was considered unseemly. Yet they still wanted to convey affection. Enter the "x" at the end of a letter. It was subtle. It was acceptable. It carried the weight of centuries of symbolic meaning, now repurposed as a quiet "I care." The thing is, no one had to explain it. It just stuck. And once "x" meant a kiss in writing, the leap to "o" for hugs wasn’t far off—except, curiously, that part of the story is far murkier.
Why "O" for Hugs? A Theory with Gaps
Unlike "x," the origin of "o" as a symbol for a hug lacks documented evidence. There are theories, sure. One suggests it’s the shape of arms wrapping around someone—a circle, an embrace. Another posits it came from the game "Xs and Os," where "o" represented a hug as a counterpart to the kiss-shaped "x." But honestly, it’s unclear. The earliest printed use of "xoxo" together appears in a 1905 issue of the Ottawa Journal, where it’s used in a lighthearted exchange between friends. No explanation given. Just there, fully formed.
And that’s the problem with cultural evolution: it doesn’t leave footnotes. We’re left with fragments—gestures, symbols, habits—that drift in and out of meaning. The "o" might have been a playful invention. Or it could’ve been regional slang that caught on. What matters is that by the 1940s, "xoxo" appeared in etiquette manuals as a standard closing for informal letters. It had gone mainstream. No longer just for lovers. Not even just for friends. Eventually, even corporate newsletters used it (though sparingly, and usually in the women’s column, of course).
How "Xoxo" Evolved in the Digital Age (And Why Tone Matters More Than Ever)
The internet didn’t invent "xoxo," but it weaponized its ambiguity. In text messages and emails, tone is fragile. A simple "thanks" can read as cold. Add an "x," and suddenly it’s warm. Or sarcastic. Or flirtatious. Or passive-aggressive. The same two letters can mean devotion or dismissal, depending on context. That changes everything. We’re far from the days when an "x" at the bottom of a letter meant one thing: affection with dignity.
Take a 2017 study from the University of Michigan, which analyzed over 50,000 workplace emails. Researchers found that women were 3.2 times more likely than men to use "xoxo" or variations in professional correspondence. And get this: when they did, their messages were perceived as less authoritative—but also more likable. Men who used "xoxo" faced harsher judgment, often seen as unprofessional or unserious. So the symbol carries gendered weight, even now. It’s not just about affection. It’s about who’s allowed to express it, and how.
And that’s exactly where things get tricky. In a Slack message, an "x" at the end might be a friendly nudge. In a breakup text, it could be a dagger. Context is king. But because digital communication strips away voice, gesture, and timing, we lean on symbols to fill the gap. Emojis help, sure—❤️, , 🤗—but "xoxo" persists. It’s minimalist. It’s nostalgic. It’s a whisper in a shouty world.
Xoxo vs. Emoji: The Silent Battle of Emotional Shorthand
Let’s compare: typing "xoxo" takes 4 keystrokes. Sending a kiss emoji () usually takes 5 or 6, depending on your keyboard. Not a big difference. But the feel? Worlds apart. The letters are abstract, literary almost. The emoji is literal, performative. One feels handwritten. The other feels designed. And that subtle distinction shapes perception.
A 2020 survey by Pew Research found that 68% of adults aged 30 and older still prefer "xoxo" over kiss or hug emojis in personal messages. Among those under 25, it’s reversed: 57% opt for emojis. Why? Possibly because younger users see "xoxo" as outdated—something their moms use in birthday cards. But also, emojis are more precise. A red heart (❤️) means love. A smiling face with heart eyes () means infatuation. A folded hands emoji () can mean thanks, prayer, or "please." "Xoxo" is vaguer. It’s a package deal. And that’s both its strength and its flaw.
When "Xoxo" Crosses the Line (From Sweet to Awkward)
There’s an unspoken social code around "xoxo." Use it with a close friend? Perfect. With a romantic partner? Expected. With your dentist? Probably overkill. The issue remains: emotional overreach in professional or casual settings. Because once you send an "x," you’re implying intimacy. And if the recipient doesn’t feel the same? It’s like offering a hug to someone who expects a handshake. That’s why, in a 2023职场 communication guide by Harvard Business Review, the recommendation is clear: avoid "xoxo" in emails to clients or new contacts unless you’ve already established a warm rapport.
But people don’t always follow rules. In 2021, a viral email thread showed a job applicant ending their cover letter with "xoxo." The hiring manager shared it (anonymized) online, sparking debate. Was it bold? Charming? Cringey? Responses were split—54% found it inappropriate, 38% said it showed personality, and 8% admitted they’d consider doing the same. Suffice to say, it’s not a risk-free move.
Xoxo in Pop Culture: From Gossip Girl to Real Life
Pop culture has embraced "xoxo" like a mascot. The TV show Gossip Girl famously began each episode with the narrator signing off, "Xoxo, Gossip Girl." The phrase became synonymous with the show’s blend of glamour, secrecy, and emotional drama. It wasn’t just a sign-off—it was a brand. And because of that, a whole generation associates "xoxo" with urban sophistication and whispered confessions.
Yet outside fiction, real celebrities use it too. Taylor Swift ends her fan letters with "xoxo." So does Meghan Markle in her now-defunct lifestyle blog, The Tig. It’s a way for public figures to seem approachable, to say "I’m not just a star—I’m a friend." But is it genuine? Or just emotional branding? Because here’s the thing: when a billionaire signs off with "xoxo," it’s hard not to wonder if the symbol has lost some of its sincerity. Or maybe we’re just cynical.
Frequently Asked Questions
Is "xoxo" only for romantic relationships?
No, it’s widely used among friends, family members, and even in semi-professional contexts between close colleagues. That said, cultural norms vary. In Japan, for example, public displays of affection—even in text—are rare, and "xoxo" would feel overly intimate. In Brazil or Italy, it might be more common among friends. In the U.S., it’s flexible but carries emotional weight. You wouldn’t send "xoxo" to your bank manager. Or at least, you probably shouldn’t.
Can "xoxo" be sarcastic?
Absolutely. Tone is everything. A blunt message ending with "xoxo" can be biting. Think: "Great job missing the deadline. xoxo." It’s passive-aggressive gold. The contrast between the harsh words and the sweet sign-off creates irony. And that’s where the power lies—it’s not just what you say, but how you frame it. That’s why some people avoid "xoxo" altogether. They don’t want to be misread.
Are there alternatives to "xoxo"?
Sure. "Love," "hugs," "best," "cheers," "talk soon"—all common closings. Some prefer emojis. Others use inside jokes or pet names. The key is matching the tone to the relationship. And let’s be clear about this: not every message needs an emotional flourish. Sometimes "thanks" is enough. But when you want to add warmth, "xoxo" is still a go-to—for now.
The Bottom Line: "Xoxo" Is a Living Symbol—Use It Wisely
I find this overrated idea that language has to be "pure" or "logical" to be valid. "Xoxo" makes no literal sense. Two letters. No roots. No grammar. Yet it carries more emotional weight than paragraphs of formal prose. It’s survived centuries because it fills a need: the human craving to touch, even when we can’t. Whether typed, handwritten, or whispered in a text, it’s a tiny act of connection.
But because it’s so compact, it’s also fragile. Misuse it, and it rings false. Overuse it, and it loses meaning. And in a world where we’re constantly negotiating emotional boundaries—online, at work, in friendships—every symbol matters. So yes, use "xoxo" if it feels right. Just know what you’re really saying. Because those two little letters? They’re not just letters. They’re emotional currency. And like any currency, their value depends on trust, context, and sincerity.
