Sticky Helicopter 

The art of spinning one's penis through the propulsion caused by ejaculating, whilst the penis is not erect.

The Sticky Helicopter
A person must begin masturbating, orgasm, but somehow retain the semen held within their penis until it is no longer erect. Once it is no longer erect, they release, hopefully forcing their penis to spin around in a circular motion.

To perform this move, place a glue stick sideways on a flat surface, place your pointer finger on one side (preferably the bottom), and push your finger down. If done correctly, the glue stick will start spinning.

If pushed down hard enough, the glue stick will "jump", causing it to spin midair.

Repeating the move multiple times within a short period of time can result in pain, especially if you perform "jumps". The move is known for being loud, so please be careful and courteous to others when preforming.

Person A: Why does your finger hurt?
Person B: I did too many glue stick helicopters.
