When you walk around a corner, typically in a building with many people(school,bank,foodlion,popeyes chicken(lots of black people there)walmart, ect)and you head just so happens to fall right into a pair of unsuspecting breasts and jiggles around in them for about 5.7 seconds or longer.
Dude! I was walking out of third period and turned the corner too sharp and ran into this big boobed slut and had and Acidental Motorboat,it was amazing!
How a boo-boo occurred dat you didn't mean to commit but were high on LSD at da time.
Hallucinogenic drugs aside, Alexander Graham Bell is said to have "acidentally" spilled caustic battery-fluid on his pants just before uttering da famous "first words spoken over a telephone", but this is a myth.
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.
