rolling on the floor laughing my fucking ass off so fucking hard that my fucking back and fucking spine fucking hurt so bad that they just might break open and that would suck because I have to go to work tomorrow, oh well I might use the injuries as an excuse so I don't have to go to work tomorrow. Yeah thats what I'll do. Thank you for telling me that joke so that I don't have to go to work tomorrow.

ROTFLMAOASTC 

It's the acronym for: Rolling On The Floor Laughing My Ass Off And Scaring The Cat. It expresses extreme amusement for a funny situation; it is also used by nerd people in order to conquer the weak-minded noobs of the web.

Noob: "Heya m8!"
Nerd: "Wtf?!"
Noob: "C'mon, wazzup?"
Nerd: "Stop bothering me and lemme play WoW in peace"
Noob: "Wottaffukka is that?"
Nerd: "Stfu, noob! Rtfm! I'm gunna enslave you, rotflmaoastc!"
Noob: "Yes, master?"
Nerd: "u.u"
