Crappy electro pop band consisting of two people RedFoo (the son of music mogul Berry Gordy), and SkyBlu (Berry Gordy's grandson.) The only reason why they're famous is because their connections. They are the worst thing that happened to music.
LMFAO are musical assclowns.

lmfao- an acronym used by many internet addicted people for they are too lazy to type it by itself. Lmfao are the begining letters of "laughing my fucking ass off".

Since most of the people who use this acronym are addicted to internet and spend most of their time sitting at a desk, the meening of lmfao has changed from "laughing my fucking ass off" to "laughing my fat ass off".
fAtSO#1: i just shit'd ma pants.
FaTso#2: lmfao!!!!!!!111!!1
