roflcopter 

A helicopter made out of ASCII art. They can turn invisible, which is why nobody sees them in the sky. No one knows how the ASCII characters can stay together, however, but people still make and fly them. Usually used for skydiving.

I took a flight in a roflcopter. All I heard was soi soi soi soi soi soi, but it was the best flight I've ever been on.

roflcopter 

It is when you are rolling around on the floor laughing that you attempt to run in circles making your legs seem like the blades of a helicopter.

STEP ONE: Lay on the ground and laugh while rolling.
STEP TWO: Start moving your legs in a forward direction, as if to walk, making sure your shoes catch enough of the floor to turn in the desired direction.
STEP THREE: Keep repeating step two until point is taken.
------When to do it-----
When something sends you into histarics you may proceed to roflcopter

ROFLCOPTER 

This Flash game started the next age of the Roflcopter saga by encouraging the development of other ASCII art animations based off of popular Internet slang. In this game (based on the Choplifter genre), one is an Elite ROFLER, manning the ROFLCOPTER, using WASD to maneuver it and the mouse to fire an unlimited supply of bullets shot from the ROFLING gun inside the Roflcopter at the enemy LOLLERskaters (ground units) and LMAOplanes (air units)
