To take someone's pillow case, turn it inside out, then continue to floss your unclean ass with it. Then turn the case back to normal and return. Then the user must smell your shit unknowingly. Normally this action is done in revenge and doesn't have to be done with a pillow necessarily. T-shirts, blankets, towels, etc are also game. happy flossing
