A meat grinder is a childhood game that I used to play with my friends. One person goes at a time, you pull down your pants and shake your weiner and balls and make them slap the sides of your leg. The person who has the loudest "slap" wins, simple as that which means they have the biggest man weiner and balls. The other game is when you call someone out to do a meat grinder where ever they are. It will make anyone laugh, even fat chicks.
"Hey you won't"
"Do I need to do a meat grinder to make you happy?"
"Oh man, that slap made my boftt jiggle."
