Sexual act with the female on top. The female does a split and inserts lubed penis into vagina. The male then grabs hold of the female's legs and spins her around rapidly, similar to that of a helicopter's blades.
Has a high failure rate, roughly 100%. Failure results in Female either falling over or vomiting, and Male losing penis.
Theoretically, a successful helicopter, if done fast enough, could generate lift for the female for about 2 seconds. There have been 3 reported cases of success, but they were all in Japan so you never know.
Dude 1: Yo d00d my girlfriend and I totally did the helicopter last night!

Dude 2: No you did not.

Dude 1: You're right. Sad face.

Get the Helicopter mug.
when a man takes off his clothes and begins thrusting his hips in such a way that his member begins to "swing" in circles like that of helicopter blades.
"I thought it would really turn her on if I were to do the helicopter, but it only resulted in alot of laughing on her part."

The helicopter is a very difficult (and awkward, don't forget awkward) but fulfilling sexual position. It is performed by the man who, while fully erect and inside the woman (... or whatever.), proceeds to turn his entire body in a circle around the woman. All the while turning his penis inside the woman's vagina (... or whatever.).
J.R.- The tricky part is making sure your member doesn't 'pop' out while you're doing this. ... And to keep from laughing. Otherwise its great.

This is when a man or woman sticks their ass as far up unto the air as possible. Then a second guy proceeds to insert his massive shlong into the ass of the first person. The person on top tries to stay as horizontal as possible while using their arms to spin themself around like a helicopter blade.

Guy 1: Want to play Soggy biscuit instead?
