When you receive a Wonderwall, a term used in Halo Reach by me and my friends (and anyone else in the know, which is about to be you). A Wonderwall happens when you melee a person from behind, known commonly as a "back beat" or "beat back" depending on the person. The term Wonderwall is derived from the song by Oasis of the same name. "Back beat, the word is on the street that the fire in your heart is out". Since a Wonderwall is a one hit kill, it always put out the fire in your opponents heart.
Me- I just snuck up on someone and Wonderwalled them, now it's on to the nextone
"Wonderwalling" is similar to rickrolling, in which a prankster (or just a unknowing guy) plays the song "Wonderwall" by Oasis on the guitar to a guitarrist.
Due to this being so overplayed, it has become a method to prank and/or annoy a guitarrist, similar to rickrolling.
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.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
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.
