rotflolmaomg 

This word is a freakin' combination of rofl, lol, lmao and omg. You sure hope it can be longer, right?
Notice the OMG at the back? It means that you're only reacting surprised after laughing like mad. Most preferably ends with a question mark.

ROFLOLMAOMG 

ROFL, LOL, LMAO, and OMG all combined into one VERY wrong word.

This is used by (or, more commonly, when mocking) extremely FUCKED UP people. Often AOL users who visit teenage chat rooms from ages 8-12 and pretend to be cool.

Phrases you may also hear from this type of people in:

Chat Rooms:
"18/f/big boobs, wanna cyber?"
"U sound hawt want 2 meet irl??????"
"I know, like, totally."

RPGs:
"HI ALL I M NEW WANT TO GIVE ME ALL UR STUFF?"
"OOOOH HOW DO I GET THAT?"
"WOW UR HIGH LEVEL I WANNA B LIKE U"

On the street:
"AAAAAAAAAAAAAAAAHHHHHHH!"
<That is all they can say, because if they say anything else, they'll be shot by sensible people and end up saying just that.

roflolmaomgtfo 

(rolling-on-floor-laughing-out-loud-my-ass-oh-my-god/get-the-fuck-out)

Definition I: Quite possibly the gayest word in this website. Used by people who think they're cool just because they made a huge word.

Definition II: Conjunction of roflolmao (used to express extreme hilarity) and omgtfo (used to express extreme dislike or disgust with the current situation or the phrase previously written. Usually used by ignorant people who do not see an underlying insult in a phrase and realize it midway through laughter.

Guy: I'm sorry I couldn't make it to your ex-wife's birthday. Didn't think she'd want me there after what I did to her.

Guy II: roflolmaomgtfo!
