XX in texting usually means two kisses—a friendly or affectionate way to end a message. It can also mean the number 20 in Roman numerals, or refer to female chromosomes in medical contexts. The meaning depends entirely on where you see it.
Why You’re Probably Here Reading This
You got a text that ended with “xx” and now you’re second-guessing everything. Is your friend flirting with you? Is your aunt just being nice?
Or maybe you saw “XX” on a pregnancy scan report and you’re trying to figure out what it’s telling you. These two letters do completely different things depending on the situation—one minute it’s affectionate, the next it’s medical information, and sometimes it’s just the number 20 in Roman style.
What It Actually Means in Real Life
When someone types “xx” at the end of a message, they’re adding warmth. It’s emotional punctuation that softens whatever came before it.
But “xx” doesn’t automatically mean someone’s interested in you. Your British friend might sign off every single message with “xx”—even to the guy fixing their WiFi. It’s a habit, not a declaration.
In medical paperwork, XX refers to having two X chromosomes, which typically indicates female biological sex. Just genetic information.
If you see XX on a document or in history class, you’re looking at the Roman numeral for 20.

How People Use It in Everyday Situations
Text Messages: “Thanks for lunch xx” or “Sleep well xx” are tacked onto the end like a signature. Some people use it automatically, others only when feeling particularly friendly.
Social Media: Less common in public posts, but you’ll see it in DMs or comment replies between friends. “Love this xx” under someone’s photo shows support.
Group Chats: One person might drop “Goodnight xx” in a friend group, and nobody thinks twice. But if only one person consistently gets the xx treatment, people notice.
Quick Replies: “Okay xx” shows you’re agreeing in a nice way, not being dismissive. Without the xx, “okay” can read as annoyed.
Tone & Context (This Part Matters)
Between close friends, xx is basically invisible. Nobody’s analyzing it.
From someone you barely know, xx can feel either really friendly or slightly inappropriate. If your boss suddenly starts adding xx to work emails, that’s weird.
In dating situations, xx can mean something or absolutely nothing. Some people are just generous with their text kisses.
Cultural differences cause constant confusion. In the UK and Australia, xx is so normal you might get it from your dentist’s receptionist. But in the US, xx typically signals actual affection or closeness. An American seeing “xx” from a British acquaintance might think there’s romantic interest when there isn’t.
Warning: Don’t match someone’s xx energy just because they used it first. If your coworker sends “Thanks xx” and you reply “No problem xx,” you might accidentally signal something you don’t mean.
Another warning: Never use xx in formal settings. “Attached is the report xx” in a job application looks unprofessional.
When You Should NOT Use This Term
Professional contacts you don’t know personally—managers, HR, clients, professors.
First messages to someone new—”Hey, nice to meet you xx” can read as overly familiar or creepy.
Apologies or serious conversations—”I’m really sorry about that xx” feels like you’re not taking it seriously.
Break-ups—”I think we should stop talking xx” sends very mixed signals.
Anything related to money—”Can you pay me back? xx” feels passive-aggressive.
When you’ve never used it before with that person—suddenly adding xx makes people wonder what changed.

Platform and Culture Notes
The xx habit is dying out with younger people. Gen Z mostly skips it and uses emojis instead—particularly 🫶, 💕, or skull emojis (💀). If you’re under 20 using xx regularly, you might stand out as old-fashioned.
On WhatsApp and iMessage, xx still hangs on with millennials. Instagram DMs see it sometimes, but way less in public comments. Twitter/X? Rarely. Discord or gaming chats? Almost never.
There’s also the username thing: xXCoolGamerXx was huge in the 2000s for online gaming. Those x’s meant nothing except “this looks cool.” Now that format is considered cringey nostalgia.

Common Misunderstandings
“X means hugs, O means kisses”—Nope, backwards. X is the kiss. O is the hug.
“XX means they like me”—Maybe, but not automatically. Some people xx everyone.
“Only girls use xx”—Not true. Plenty of guys use it too, especially in the UK.
“More x’s means more feelings”—Kind of, but someone sending xxxxxxxxxx is either joking or doesn’t understand how this works.
“XX in Roman numerals is outdated”—Still used for Super Bowl numbers, book chapters, and fancy event dates.
Thinking pregnancy scans use “xx” casually—Medical contexts are totally different. XX on an ultrasound report is technical language about chromosomes.
FAQs
Is sending xx ever rude?
Yes, if you’re using it in serious topics, formal contexts, or with people who don’t text that way.
Does xx mean the same thing everywhere?
No. British and Australian people use it way more casually than Americans.
Can xx be sarcastic?
Yes. “Oh sure, that’s just great xx” is dripping with sarcasm.
What if someone stops using xx with me?
Could mean nothing—maybe they’re busy or typing fast. If everything else seems fine, don’t overthink it.
Should I use xx if the other person does?
Not automatically. Match their energy only if it feels natural and fits your relationship.
What’s the difference between xx and xo?
XX is two kisses. XO is one kiss and one hug. XOXO alternates between both.
Wrapping Up
XX is just two letters doing a lot of work. Most of the time, it keeps text messages from feeling cold. Sometimes it’s medical information. Occasionally it’s an old number system.
Pay attention to who’s using it and how. Don’t assume. Don’t overthink. And when in doubt, skip it—nobody ever got in trouble for being slightly less affectionate in text than they could’ve been.
