HMU

HMU means “hit me up.” It’s a casual way of saying “contact me”: text me, call me, or send me a message.

What does HMU mean?

HMU is short for “hit me up,” which Merriam-Webster defines as a request for someone to contact you. It’s often used in social media posts and group chats to invite anyone interested to get in touch: “Selling two concert tickets, hmu.”

It can be completely practical, or it can carry a flirty undertone when sent to one person, like “hmu if you’re ever in town.” As with wyd, context and timing do a lot of the work.

How to use HMU

• “Anyone want to play tonight? Hmu.”
• “Hmu when you’re free this weekend.”
• “If you need help moving, hmu.”
• “Selling my old bike, hmu for details.”

HMU vs. LMK

LMK (let me know) asks for a specific answer or update. HMU is more open: get in touch, whenever you like. “Lmk if you can come” wants a yes or no; “hmu if you want to hang” leaves the door open.

Where HMU comes from

“Hit up” meaning “contact” or “get in touch with” is well-established informal American English. HMU is its texting and social media abbreviation. Merriam-Webster doesn’t give a first-use date for the abbreviation, and none is documented.
