A pathetic guy who acts super horny and confident in texts, DMs, or when he's talking big in person, but instantly freezes, ghosts, backs out, or gets awkward the second a woman actually wants to fuck. All bark, zero follow-through — he teases like he’s ready but turns into a timid little bitch the moment a woman accepts his persistent but hollow offer.
"Girl, he was telling me all the ways he wanted to fuck me in my DMs but when I ran into him at that party it was obvious he was a shy dick - wouldn't even kiss me."
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.
