Sudden Onset Poop/Pee Syndrome

An extreme disorder common among athletes. Also, being in a crowded place makes it more likely.

Occurs when the victim finds himself or herself thinking about using a toilet soon, but for some reason is forced to be delayed from using it. The result is that the sensation of having to poop/pee becomes unbearable worse than before.
The swimmer got out of the pool to go piss during the workout and got a severe case of SOPPS when he realized that he couldn't untie his suit to go.

When waiting in line for a urinal in the bathroom during the seventh inning stretch, I got SOPPS.
