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!!!

hellacopter 

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.

bellycopter

The art of grasping the penis by the root and swinging it round like the rotor blades of a helicopter.

"Giles failed to make a good impression at the wedding reception after he demonstrated the bellycopter to the mother of the bride".

Hellacopter 

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