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.

When one is unsure of whether or not their fart is a shit, but continues to push it out anyway. The risk greatly outweighs the rewards, but we do it regardless.
Sitting in front of the TV, I felt a fart and pushed. I survived another round of shit roulette, but one day I won't just fire a blank.
