This is the act of trying to handstand with no bra on. for a lady with large breast it may be dangerous and could cause black eyes, suffocation, unconsciousness or carpet burn to the nipple.
boyfriend; Whats the red mark on your nipple?
Girlfriend; well its a burn, a carpet burn!
Boyfriend; I told you to stop fultiging in front of the window.
Girlfriend; but i like seeing old pervey Clive fall off his bike when he looks in the window!
