HMU means “hit me up”
HMU stands for “hit me up,” a casual way of saying contact me: text me, call me, DM me, or get in touch when you want to make plans. Dictionary.com defines it as slang used as a request or invitation to contact the person who wrote it. Oxford Learner’s Dictionaries defines the phrase “hit somebody up” as simply “to contact somebody.”
It’s written hmu or HMU, and the capitals change nothing. The phrase is older than the abbreviation. Cambridge still lists an earlier American sense of “hit someone up,” meaning to ask someone for something. Dictionary.com says the short form spread in the early 2000s along with other internet shorthand, and the earliest Urban Dictionary entry for it dates to April 2009.
What it means in a text, a DM or a chat
The meaning stays the same everywhere. What changes is what the person wants you to do next. Read the words around it, because they usually tell you whether it’s a plan, an open door or a polite sign-off.
- “hmu when you’re free this weekend”: they want to make a plan and they’re leaving the timing to you.
- “ok cool, hmu”: often just a friendly way to end the conversation. Nothing is scheduled.
- “hmu?” with a question mark: they’re checking whether you’ll get in touch, or asking you to reach out first.
- “hmu in chat”: in a comment section, group or game, it means move this to private messages.
- “bored. hmu” on a story or caption: an open invite to anyone who sees it to message them.
- “any questions hmu” on a listing: a seller asking buyers to message them.
- “hmu if you need anything”: support, not plans. They mean it, and they’re leaving the next step to you.
Is HMU flirty?
On its own, no. Between friends it’s about as neutral as “text me.” It turns flirty because of who sends it and when. Dictionary.com notes it can signal interest in continued contact in dating, including after you’ve met someone online.
A few signals help. A match who says “hmu” after a long, good conversation is interested and wants you to make the next move. A late-night “hmu if you’re up” from someone you’ve been flirting with is usually an invitation to keep it going tonight. A bare “hmu” from a stranger who has said nothing else isn’t really an invitation to anything. You don’t owe that one a reply.
If you can’t tell, ask. “Hit you up for what?” or “Is this a coffee hmu or a just-chatting hmu?” is a normal question, and the answer saves you guessing.
How to reply to HMU
The best replies do one thing the original message didn’t: they name a day, a plan or a question. Pick the one that matches what you actually want.
Conversation starters for meeting someone new
- You want to make plans: “Bet. Tacos Thursday after work?”
- You’re interested but busy: “Swamped till Friday. I’ll text you Saturday morning.”
- You’re not sure what they mean: “For sure. What did you have in mind?”
- Flirting back: “Careful, I might actually do that. Free Friday?”
- Keeping it friendly, not romantic: “Down for a group thing! A few of us are doing trivia Wednesday.”
- Not interested: “Thanks, but I’m going to pass. Take care.” Or just don’t reply.
- A friend going through something: “I’m around tonight. Want me to call?”
How to use HMU yourself
A bare “hmu” puts all the work on the other person. They have to decide what to suggest, when, and whether you meant it. Add a reason and a time, and you’ll get far more replies.
If someone said “hmu” to you weeks ago and you never did, it’s not too late. Mention the gap in half a sentence and suggest something specific.
How to reply after a long pause
- “hmu if you’re down for the farmers market Saturday”
- “Landing at 6. HMU when you’re out of work and we’ll grab food.”
- “HMU ASAP, I need your opinion on something before 5.”
- “Finally hitting you up like I said I would. Still want to try that ramen place?”
Related slang you’ll see next to it
HMU travels with a few other short forms. Most mean roughly the same thing with a different push behind them.
- HMU ASAP: contact me soon. Something is time-sensitive.
- hmu if you’re down: an invite, with no pressure to say yes.
- hit me back: reply to me, usually after you missed a call or text.
- LMK (let me know): send me an answer. Wiktionary lists it next to HMU.
- DM me: the same request, specific to the app you’re on.
- hook me up: a different meaning. Dictionary.com lists it as another reading of hmu, a request to be connected with something or someone.
When not to use it
Dictionary.com calls hmu casual, so keep it where casual belongs. Skip it in work email, job applications, messages to a new manager, and with older relatives who may read it as a typo.
Don’t send it as your whole first message to someone you just matched with or found online. It asks them to do the work of starting a conversation you started. Ask a real question instead.
One more thing: in weddings, film and photo shoots, HMU means hair and makeup. Wiktionary lists that as a separate meaning. If a call sheet says “HMU 7am,” nobody is asking you to text them.
HMU is also an app
If you found this page searching “hmu in chat,” you may have meant something else. HMU is also the name of an app for adults 18+ who want to meet people and actually talk, for friendship, dating or both. Every request starts with a real first message rather than a blank “hey,” and Meet Now pairs you with one person for a five-minute chat that starts from the same prompt. It continues only if you both choose Keep. It’s free on iPhone and Android, and you can report or block anyone.
