WhipBack, also known as "WhackBack", is a pain-inducing game played by teens and young adults who use leather belts to create self-inflicted welts on their backs.
I laughed my ass off all night because Billy wouldn't stop playing WhipBack.

It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
