Similar to that of a stunt double, a stunt butt is someone who replaces a male porn star when the pounding becomes too intense or a fuck stunt may be too dangerous for the star butt. A stunt butt can be identified by a gaping anal orifice and bruised buttocks. They are willing to take exorbitant amounts of cock to their anus for the greater good of a porno. Stunt butts must continuously adapt to and perform new fuck tricks brought into the porno community.
Stunt butt credo: "Fuck it"
Director: "CUT! O.K. Peter why don't you take five and we'll get the stunt butt in here for the flying sausage dive."
This condition occurs when a female who is currently on her menstrual cycle, suffers from severe hygiene issues. This leaves a scent of copper which can be smelled without trying. Also, it creates a rust colored lining in the persons underwear, therefor creating the appearance of a copper bottom.
That girl ain't showered in so long that I can smell the wishing well in Rusty Copper bottoms jockeys!
