Psycho-magnification is the process by which interpretations of events/thoughts/action get magnified or exaggerated exponentially (till a point at which it defies logic) as the thought passes through different psyche levels.
Process example : Person 1 to 2 : "Mike was stung by a bee"... Person 2 to 3 : "Mike was stung by a giant bee"... Person 3 to 4 : "Mike was stung by a giant man-eating bee and escaped only because Batman saved him."... Person 4 to 5 : "Mike is a giant man-eating bee and he ate Batman"
Mike's experience with the beebite was subject to a brutal amount of psycho-magnification.
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.
