What Does 'HMU' Mean?

Does internet slang leave you puzzled? Brush up on your acronyms

HMU is an online acronym for "Hit Me Up." It is used to say "contact me," "text me," "​phone me," or otherwise "reach me to follow up on this." It is a modern shorthand way to invite a person to communicate with you further. Basically, it is internet slang, which is an outgrowth of online chatting, mobile texting, email, and instant messaging.


HMU used to mean "that person asked me for something," as in "David hits me up for a small loan every Friday night." However, the expression has morphed to mean "communicate with me further."


HMU can be spelled in all lowercase as hmu. Both uppercase and lowercase versions mean the same thing, and you are welcome to use either given the internet's relative informality. Just avoid typing entire sentences in uppercase, as that is considered rude and is interpreted as shouting online.

Example of HMU usage

  • (User 1) Cristina: I have two e-coupons for 20 percent off at Jinx.com. Does anyone want one of these coupons?
  • (User 2) Ramira: I'll take one coupon! I could use a Jinx shirt.
  • (User 1) Cristina: OK, hmu with your email address so I can send the coupon to you.

Example of HMU usage

  • (User 1) Abidola: Jay! HMU later for those tickets. I have them in my car.
  • (User 2) Jay: Cool.  How about I meet you at your place after 5 p.m.? I'll bring cash. 
  • (User 1) Abidola: kk sounds good

Example of HMU usage

  • (User 1) Tuan: Dude, I need to borrow your ID card.
  • (User 2) Daniel: My ID card? What are you doing?
  • (User 1) Tuan: Intramural hockey. I need to show a school ID before they let me on the ice
  • (User 2) Daniel: Gotcha. K, HMU at lunch. I'll be at the Subway in CAB building at 11:30.

Example of HMU usage:

  • (User 1) Sheldon: Hey, I could use some good advice on winter tires. I'm thinking of getting some for my daughter's car.
  • (User 2) Kaveh: I read a good article on that. Sec... maybe I can find it in my bookmarks.
  • (User 1) Sheldon: Great, HMU! Please send me that link when you can.

The HMU expression, like many other internet expressions, is a part of online conversation culture. Like any human group behavior, speech and language expressions are used to build cultural identity through customized language and unique conversational expressions.
