One who likes to fuck face down in the pillow and ass up in the air. Due to the brutality of the ass plugging, the receiver may be unable to shit for days. The pillow is used to bite on to help numb the pain of the initial thrust. Many who push the pillow will wake up with pillow face and possible dental damage.
