In the oscillations between struggling not to shit and feeling perfectly fine (somewhat analogous to contractions during child birth), the brown flash is the temporary but dire need to take a shit. Often results in sweating, heavy breathing, and a clenching shut of the asshole to prevent shitflow.
After 2 hours of holding in a shit I was brown flashing incredibly hard. My feelings of intense need to shit were becoming closer and closer together and I knew if I did not shit soon I would ruin a pair of innocent underwear.

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.
