When a group of men get together and stack their scrotoms up on top of each other. Like a Totem Pole only with scrotoms instead of totems. See also, sack stack.

when someone out of anger uses their scrotum as a weapon, thus by rubbing someone elses belongs on it or touching the sweaty sack then touching a desired person.
he got so mad at frank that he took his sunglasses and scrotamised them
