The apendage used in the initial creation of the Filthy Snowball. Usually a male testical post anal coiltus And post Snowball.
When the person whose bum is used as a reciptical for the semen when performing the Filthy Snowball, turns around and licks the concoction off the filthy gonad.
I thought all the fun was over after the Filthy Snowball but I was pleasnatly surprised to not need to shower right after when my hockey buddy gave me a Filthy Snowcone. Thanks hockey buddy :)
