When one is 90% sure they are going to fart but there is an outside chance they may shart, so just to be safe they seek out the nearest toilet.
If you'll excuse a moment, I have to go make a safety-shart. I don't want a repeat of what happened last week when I shat my britches.

When you really really have to take a shit so you're rushing to get home so you put the brown siren on top of your car to let everyone know to get out of your way.
Robert: Shit! Why did we have to go to the Indian restaurant on the other side of town. I don't think I'm gonna make it home. Put on the brown siren for fucks sake!
