While in the act of having sex with your girlfriend who cheated on you, you spray pepper spray or rub hot sauce on the condom and continue to have sex with her.
Hey did you hear Mark found out Veronica cheated on him. He gave her the old payback pepper jack. That shit was spicy.
basically a payback for the female after getting donkey punched. The female gives the male a blowjob and when he ejaculates she spits its it in his face and then proceeds to punch him as hard as she can in the face.
girl 1: "me an my boyfriend are not speaking at the moment"
girl 2: " aww, what happened?"
girl 1: " he donkey punched me, so i gave him the payback power punch"
girl 2: "hilarious, well it's only fair."
