Get the LMFAO mug.
No, this isn't 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 that's like picking the cleanest dirty shirt in a shit-pile.
Jim: "Hey did you hear the new LMFAO song?"
Al: "No I have a taste in music and you sound like a 13 year old girl."
Get the LMFAO mug.
LMFAO is an acronym for “Let My Fucking Anointing Overflow”, used primarily by BadChristians and other Christians who are not offended by profanity.
I am preaching tonight’s service guys, LMFAO!

When you are laughing to the point that your (expletive) rear end is being forcibly removed from the rest of your body.
rear end1: why did the chicken cross the road? to get to the other side.
rear end2: thats a good one. lmfao. im laughing so hard im being removed from the rest of my body.

Abbreviated form of "Laughing my fucking arse (or ass or other) off" commonly used in online/networked gaming and in chat rooms, similar to, though more expressive and indicating greater laughment than lmao (laughing my arse (etc.) off).
