the wind grinder is usually performed at male sleepovers when the first person falls asleep the others prop him up and arch him then they go get a vacuum and stick it up his ass as one male sticks it up the sleep males ass another reaches down his throat and grabs the long end of the vacuum the pulls it through his mouth then the males that are awake must perform a soggy waffle to see who gets their meat wind grinded. THE WIND GRINDER WILL RESULT IN DEATH
