HMU stands for “hit me up”. Most commonly used among teenagers in social media. They will use the word in order to express to their followers that they are single and would like a boyfriend/girlfriend. So basically, telling someone to text them and try to get together with them.

Get the HMUmug. Stands for "Hit me up." Simply means "call me," "text me," or some other form of "let's get in contact" with no other connotations. The exact meaning can usually be gotten from context.
