A shit that comes in three stages and is super-annoying because of the fact that you have to take a shit three times.
Tends to happen after not shitting for a while, eating a big meal, when you are sick, or when you've eaten some crappy food.
Stage 1: Normal shit: Comes out looking normal, but all at once.
Stage 2: Half-solid shit: Comes out all at once and is only half-solid.
Stage 3: All liquid: The shit just pours out of your ass in a shit-smoothie. Ass-washing is required.
Damn, I hate taking a 3-stage shit.
