Switch

A friendly game where you and friends put one finger in your mouth and another up your butt. When someone says switch, you switch fingers. Forms of “Switch” can be played with varying peoples mouths/butts. And you can even use different fingers each round.

You: “Hey, Joe wanna play a game of switch?”
Joe: “Sure thing bro!”
*one finger enters mouth (preferably pointer finger of one hand)
*another finger enters butt (preferably pointer finger of other hand)
Joe: “SWITCH!!!”
*fingers switch
