The ultimate gang bang sex move involving six dicks and one vagina. It is categorized as a TVTA (triple vag, triple anal)where three dicks are put in the vagina and three dicks are put in the ass. The result is a fan of dicks that would resemble the fan on the tail of a peacock.
I've never seen The Peacock, only in my mind. However, I picture the character Matt Stone played in Orgazmo yelling "Time for the peacock! Dude, we're gonna put three dicks in her vag and three dicks in ass!"
