roflmaoasc 

Roflmaoasc is a variant of the well known roflmao(:rolling on the floor laughing my 4$$ off) and means:

rolling on the floor laughing my 4$$ off and scaring the cat

..which adds even more to the greatness of the laugh, resulting in the kind of laugh many people have died happy from

Cats don't like this kind of stuff, others find it funny, but most are too scared.

ROTFLMFAOASTD

Rolling on the floor, laughing my fucking ass off, and scared the dog

Usually found in Instant Messages, typed when someone has said something REALLY funny, like, "Why won't my new home-built PC start up? Should I have used those little brass stand-offs between the case and the motherboard?" The proper reply to such stupidity would be ROTFLMFAOASTD!
