GEBS means "Giant Elephant Balls". Not many people could be able to have GEBS. The only pair in the world is found on a Shelby Rema. You would have to have some hard skills trying to fit them onto a bus every single morning. Most often GEBS are found on weird young teen girls. There is no way you can get rid of GEBS, you are stuck with them for life. Be proud if you have them!
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.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
