More severe than a Shart but not full out, colon emptying, pants blowing bowel evacuation. Symptoms include a squishy feeling between your butt cheeks, distinctive bowel aroma, and possibly stickiness between one's drawers and ass cheeks, depending on the consistency of the "pudding" let loose from one's colon.
ME: "What's that smell? Did you Shart?"
You: "Shart? No, but that burrito I had at the Cubby's 100 miles back might have given me Puddin' Pants. We'll have to pull over so I can check."
Fecal matter lacking physical fortitude. Apt to release through the anal sphincter from the darkest crutch of the colon at any given moment, and likely at the worst possible time.
*In the middle of a business meeting*
The Boss - "Need a moment? That fart sounded wet."
You - "That'd be great. I've got pudding in my pants."
Someone or something that bites your ankles.
To a postman, an ankle biter is often known as a dog.
To an adult, an ankle biter may be a toddler.
To hikers, an ankle biter is sometimes a tick.
And so on.
