wearing two pair of tighty-whitey underpants in an attempt to warm the balls

The act of inserting one or more testis into the anus of another being. This takes finesse and careful planning. Mistakes, as you can imagine, would have consequences.

The Snack Pack Sack Attack is quite simply, the result of a young man dipping his testicular sack (ball sack) into a snack pack (pudding), preferably tapioca (for the joy of texture), and then dipping that sack into a young womens mouth (teabag)
ball sack + snack pack + teabag = YES

Another word for a male's jock strap
