L.O.M.F.A a misspelling of lmfao but was given a defination used by a few players of runescape. The defination is laughing out my fucking ass. It is when you are laughing really hard in real life. Some people use it in the W31 Barr0ws friends chat in the game.

Look, my friends ate ice. Sometimes it's really hard to admit your friends eat ice. It's just such a terrible thing to do for your teeth and for everyone's ears. BUT (but) if they do (if they do) you should (listen closely) say (speaketh) LMFAI! It's a pain free and quicker way to admit your friends eat ice. It's like saying passed away instead of dead, it's hard to talk about. So say LMFAI instead of "my friends eat ice" and the admission will go by pain free!
Stacy: Tell me something you've never told anyone. Kelly, you first.
