The Poo Poo Hot Pot (AKA the Boston Ball Warmer) is a New England phenomena. Named for a Cambridge Massachusetts eatery, whose legendary cuisine led to original episode, a Poo Poo Hot Pot occurs when an individual farts in very cold weather whilst wearing layered clothing. A very slow yet persistent trail of steam is released from the backside of the potter's waistline in a fashion reminiscent of a boiling pot or chafing dish. A warming sensation has also been reported extending as high the shoulder blades.
The weather was unbearable but luckily for me, I released a poo poo hot pot shortly after getting in line which made the situation much more comfortable, for me.
"Poop or get off the pot" is a more polite way of saying 'Shit or get off the pot.' It's not very eloquent but it gets the message across. My parents knew all the dirty words and phrases but would say things like 'did you just let off wind?' rather than 'fart'. Saying fart in our home whenI was young was not a good idea.
