Lmfao

[Tina]

Laughing my fucking ass off

[Couch Potatoe]

No, this isnt the fucking acronym.
A terrible band that takes a synthesizer and 2 microphones and a computer and makes millions of dollars from poorly written lyrics and said tools. Their hit song, Party Rock Anthem, neither sounds like a party or rock, more like a rave or hemorrhaging piece of shit. Do not listen to them. Their only half-decent song is I Am Not a Whore, and thats like picking the cleanest dirty shirt in a shit-pile.

[Britney]

[Little_Girl]

When you are laughing to the point that your (expletive) rear end is being forcibly removed from the rest of your body.

[Little_Girl]

[Zipporah Schumaker]

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

[Jason Yan]

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.

LMFAO is an acronym for “Let My Fucking [Anointing] [Overflow]”, used primarily by BadChristians and other Christians who are not offended by [profanity].
