Anal digging,,,the game

its where you attatch a vibrating dildo to your forehead and try to make your partners poop into puzzle shapes, where after the other team has to put the puzzle together using anal lube and a gardening shovel to slide the peices into place...once they're in place both teams sift through the dung pile to see who can find the most undigested food particles

Me & my friends really like it...its great for bonding, but is it normal ??
