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
