Number 3 

Pooping and vomiting at the same time. The vomiting is often done in an adjacent trash can, but when one is unavailable, the person has no choice but to de-throne and vomit in the dirty poo water toilet or else on the floor. Neither option is desirable, that's why people keep trash cans next to the toilet. Also known as taking a Lauren.

Last night was pretty rough, I just took a messy number 3. I need to brush my teeth.

Number 3 

When a woman has to go to the bathroom to change her tampon/pad, or "push out some blood."

Pull the car over honey, I need to use the bathroom. Number one or number 2. Neither, number 3- I need to change my tampon.
