Lmhi stands for let me hit it. It is what you say to a desperate girl who uses an internet dating app such as bumble or tinder because she wont throw leg.
Man: Hey whats up girl. Lmhi?

Girl: Dude what are talking about haha?!?

Man: LMHI!

Girl: *deletes app* says to herself, im never going to get a bf.
