Yuh Yuh Yuhhhhh was created in a mashup that was performed/recorded by Why Don't We. The mashup consisted of Gucci Gang and Ten Million. Yuh Yuh Yuhhhhh was said by Corbyn Matthew Besson, 1/5 of Why Don't We. Yuh Yuh Yuhhhhh means 'yeah, yeah, yeahhhhh.'
This is how it was preformed:
Gucci Gang, Gucci Gang, Gucci Gang, Gucci Gang
Corbyn: Yuh Yuh Yuhhhhh
Gucci Gang, Gucci Gang, Gucci Gang, Gucci Gang.
(just a snippet of their mashup rest can be found on their Instagram, @whydontwemusic )
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.
