What does HMU mean?
HMU is a very widespread internet abbreviation that can stand for multiple things, depending on the context.
The original, most used meaning behind it is “Hit Me Up” used to motivate people to search for your company either by text or by a phone call. Another sense it may have is “Hook Me Up” utilized in scenarios when one asks for contact with someone.
