Parrot

The act of a male placing his testicles on a unsuspecting persons shoulder who is sitting down. Also can be done by a woman who places one of her breasts on a persons shoulder. Feel free to make a parrot noise if you wish to put the cherry on top.

Also known as Parroting. Ex: I love parroting people.

While Craig was working on his computer, Greg sneaked up behind him and placed his parrot on his shoulder.
