A game boomers used to find interesting and fun.
The act of putting one’s thumb in thumb in the mouth, and the other thumb up the ol’ bum hole, and switching both thumbs vice versa very quickly
Jommy: you want to play Nintendo switch?
Sonji: the game where you switch thumbs?
Jommy: oh fuck yeah bud!!
