A massive pillow that extends beyond the heightness and width of the individual laying within the comforting boundaries of the fluffy device. The pillow is massive and amazing. It dwindles the effectiveness of any man's cuddlebility as the pillow does not move, snore, or drool. Often loved by preggos.
