Based of an ASCII picture and now a flash game. The rofl copter has its spinning LOL propellers and occasionally drops a WTF bomb or an OMG missile and the LOLerskaters below or the LMAO planes.

When playing any FPS - First Person Shooter - the player, usually a noob player, spins in a circle shooting wildly. Preferred weapons to use are machine guns, but other weapons such as rocket launchers or auto shotguns can be used successfully. To do a successful ROFL COPTER, the player must actually score a kill.
Player 1: Dude, i just pulled off the most 1337 ROFL COPTER EVER!

Player 2: Your such a noob

ROFL Copter is when someone is sitting on a computer chair, such as the one i am in right now, that rotates about at the stem. A ROFL Copter is when you laugh so hard, you actually spin out of the chair.
OMG, I found this flash toon, and I ROFL coptered.

In a game:To be in a flying vehicle
(More specifically a helicopter)
and spin around randomly and shoot like you have LOST YOUR GODDAMNED MIND and say SOISOISOISOISOI while doing so

Not in a game:If someone says something really funny and just say it...but most people say ''My roflcopter go soisoisoisoi'' instead of just roflcopter,but thats something completely different
In a game example:
GameDestroyer:MY ROFL COPTER GOES SOISOISOISOISOISOI *Shoots randomly*

(HEADSHOT!)

Scared dude:He actually killed someone with that?

Not in a game:
FunnyGui:And you know what I said to him?

LaughingGui:No

FunnyGui:WELL AT LEAST I AIN'T YO MAMA

LaughingGui:ROFLCOPTER

1.The ROFL copter shoots a LOL bomb or a WTF missle at the LMAO planes below. The ROFL COPTER goes soi soi soi.

2. The act of spinning and shooting crazily. You can only call it a ROFL COPTER if you get a kill by using it. If you get a head shot while using said ROFL COPTER you get l33t points.

3. The act of (R)olling (O)n (T)he floor (L)aughing.
In Halo 3 i was using the ROFL COPTER and i shot a n00b in the head.

The other day i was ROFL COPTERing and i slapped Maira in the face, it was so l33t... she cried like a little baby bitch.
