LMFAOTICS 

Laughing My Fucking Ass Off Till I Can't Stop.

An acronym that is used online, to express hardcore laughter at something extremly funny said by someone else.

Jane: i met this guy in the club and he was trying to make a pass at me...

Jason: oh really, well, what did he say?

Jane : he said "baby, you so hot, they should turn off the heating in this place!"

Jason: LMFAOTICS!!! i can't believe he was that lame!
