ROFLLMAONHAHAANDWSTC

It's what geeks do when they got no time. Make up long words e.g:

rolling on the floor laughing, laughing my ass off nearly having a heart attack and nearly dying while scaring the cat.

Basically its just when people go over the top about a little subject. Making fun of them - taunting.

Guy:lol! that was funny, the guy fell over
Guy2:ROFLLMAONHAHAANDWSTC that was funny.. (not..)
