cock-o-copter 

(v) The act of gripping the base of one's flaccid penis and twirling it around (mimicking the whirling motion of a helicopter blade) when jumping from a tall structure; usu. in an attempt to slow one's descent.

The cock-o-copter is thought to have been invented by Scotsmen in the early 1400's, as an effective method of flying/gliding when combined with the parachute-like properties of their kilts. The overall goal is an effect much like that achieved by modern-day airships (blimps).

Did you see how good Jon's cock-o-copter was off of that bridge? He almost levitated!

Kentucky Cum Copter 

The act of tightly tying a cord of some fashion (nylon, twine, hemp, etc.) around the shaft of one's penis. The other end of the cord is tied around an object, preferably quite heavy.

The individual then spins in either direction as fast as he can manage, making the weight come up in the air as he does. This continues until the man finally attains climax, and splooges all over the surrounding area.

Often used as both a workout and a way to sabotage precious space.

Guy 1: "Dude did you hear about how well I pulled off that Kentucky Cum Copter the other day?"
Guy 2: "Yeah bro... Your tic tac dick could only hold ten pounds, I was doing 45's the other day!"

"I'm going to Kentucky Cum Copter the crap out of your guys' room when you're not looking!"

"I'm a little bi-curious, so I like to Kentucky Cum Copter in the showers barefoot"
