LMHAO

Used instead of lmao, it means:Laughing My Hairy Ass Off. Used when something is exceptionally funny, or when being sarcastic.

Jon:- Come on man, that shit was funny, just give me some props!
Mark:- Oh okay then. LMHAO. ¬_¬

James:- ...so then she actually runs out naked!
Mark:- LMHAO!, gutted to her!
