Something like the poop shuffle, going stiff is a tightening of all muscles in body to keep the shit held in your arse until you have reached the toilet, you can easily identify when someone is going stiff as they look like they are waddling very quickly while walking.

light as a feather, stiff as a board

Light as a feather and stiff as a board is a sexual game played by teens everywhere. This game usually involves multiple partners, although can be played with only two people. Usually the male will lay on the ground blindfolded without clothes while the other members of the party surround him. Now this member can be a female, but traditionally the role is played by male. The other members of the party now use paintbrushes and dip them in warm cups of water, and then paint the middleman with water. This goes on for approximately 2 minutes. During this time members of the party will also take markers and draw a “wigi” board on the middle man’s stomach and chest. Once the wigi board is complete one half of a crayon is placed on the middle man’s board. After 2 minutes the other members then start lightly touching the middleman with various objects and things such as their fingers, silverware, and other body parts. This continues as a tease until the middle man is as “stiff as a board”. Once stiff as a board members around the middle man begin to chant the words “volo postulo Adveho nobis” in unison. At this time all of the lights should be off. The game is played in many ways. Some participants sexually tease the middle man until he ejaculates and then read the encoded message from the wigi board. Others will finish the game by continuing to chant until spirits intervene. In both cases the middle man should ejaculate which signifies the end of the game.

Girl 1: What do you want to do tonight?
Girl 2: I don't know I'm so bored!
Guy 1: I know! Let's play light as a feather, stiff as a board!
Group: Yeah!
