When you've been harboring a major cable so long that your body starts to forcibly reject it, giving you the feelings of contractions in your anus. Often accompanied by ass sweat, and anal convulsions.
Man I've been holding off on dropping this bad boy off so long, I'm starting to have poop contractions!
An overwhelming sense of pain, panic, cramping, and cold sweats that sweeps over someone when they are about to have diarrhea...especially if they are forced to hold it longer than they need to.
The feeling comes and goes, but gradually increases in frequency...like when women give birth...but this time you are giving birth to a giant wet shit.
Jeff's poo contractions became stronger and more intense as he searched for a clean public bathroom. Thankfully, his sphincter was strong and held back the flow.
1. Describes a phenomenon when you are pregnant. Feels similar to birth pangs, you think you are about to give birth, but turns out you just needed to shit. The TY contractions typically produce feces that are abnormally massive, very offensive odour, that results in an emergency call to the plumber because it breaks most standard home toilets.
