“I lay there," she wrote, "annoyed that I was getting fucked by a guy with Yeti pubes and a mushroom dick like the character in Mario Kart." -Stormy Daniels
A condition in which the corona and frenulum of the penis (the "mushroom"-esque part) are significantly wider than the shaft. Sometimes a result of poorcircumcision.
I'm so glad I'm not circumcised, that means I get to keep my my foreskin pulled back from the mushroom part of my mushroom dick thus avoiding "dick cheese", then push it back over whenever I want, and STILL not have any fucked-up cosmetic surgery on my cock
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.
