Fellacopter 

When a gentleman spins his flacid/semi-flacid penis around multiple times, resembling the spinning blades of a Helicopter

Matt: *Spins cock violently*

David: Dude, stop Fellacoptering me!

Bellacopter 

When a male, usually in the showers, grabs his shaft and swings it round in the motion of a helicopter rota-blade. Lots of fun with more foreskin.

Man did you see Bruce Forsyth in the shower he had so much foreskin I thought he was going to take off with that Bellacopter!!!

it looks just like a helicopter, but it kicks ass

In my hellacopter i flew into outer space, ate some children and whaled on my guitar. I don't know any helicopters that would let you do that. Helicopters are whack.

The process of swinging your dick around in circles making it appear as a helicopter to those watching.

Hellacopter 

When a male stripper swings his penis in a circular motion without using his hands.

The big black stripped gave me a lap dance and a hellacopter 6 inches from ym face.
