ninja punch

In the act of giving anal sex, while all the lights are off use a dildo instead of your wang and sneak infront of the reciever while they think you are behind them, and in one quick movement turn on the lights and punch them in the face screaming "ninja punch bitch!"

Man that chick was so rude, i ninja punched her and called it good.
