Its when you take a big solid shit kicking its way out of your ass, the head sticks out of the water and you think (i'm gonna need a plunger to beat this fucker down), thers no need to wipe, and when you fush it disappears in a cloud of brown mist!

When you take a fast, odorless, silent shit that has almost no residue when wiping.

When diarrhea or mexican food sneaks up on you at a random time.
