Like brain freeze when one eats or drinks a frozen food or beverage too fast and they feel a suddennly painful sensation, brainskeeze is in reference to when a girl or fag sucks a dick too fast and takes in too much skeeze(sperm,skeet, giz, etc.) in which she will too feel that same startling painful sensation as experienced with brainfreeze.
Woman or fag: "Hmmm...Hmmm oh no... not again... I was suckin the dick too fast... oh shit! (clutches forehead in pain) it hurts I gots brainskeeze, oh shit it hurts ima hoe ima bitch!"
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.
A "human" that spends so much time playing video games that their posture is level nerd neck. Everytime anyone goes tryhard they hunch down and their neck gets longer there fore a nerd neck is always hunched down cause they're always going try hard. In other words a nerd neck is a try hard, since their neck is 100% longer than the average human being due to playing too many video games and taking them serious, nerd necks are not even considered human anymore but something more sad. Nerd necks are often found on fortnite, their natural habitat usually being tilted towers.
