HMU is an online acronym for "Hit Me Up." It's used to say "contact me," "text me," "​phone me," or otherwise "reach me to follow up on this."

It's a modern shorthand way to invite a person to communicate with you further, but just not right now. HMU is internet slang that might be seen used during online chatting, texting, email, and instant messaging.

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.

Note: This acronym has also been used in jest to mean "Hold My Unicorn," but it's not the most common usage for HMU.


HMU used to mean "that person asked me for something," as in "David hits me up for a small loan every Friday night." However, sometime in 2009, the expression morphed to mean "communicate with me further."

The "Hold My Unicorn" version of HMU might have been first seen in 2010 on Urban Dictionary.


HMU can be spelled in all lowercase as hmu. Both uppercase and lowercase versions mean the same thing, and you're welcome to use either given the internet's relative informality.

Just avoid typing entire sentences in uppercase because that's considered rude and is interpreted as shouting online.
