A Poop Barrel (or in polite terms, Parrel, or the P-word) is referred to an individual who resembles a gigantic ball thanks to his/her extreme obesity. Poop Barrels breath loudly and are thought to store their waste inside themselves for at least 2 years, like barrels of poop. These creatures are capable of destroying infrastructure if rolled from a hilltop. Researches have shown that poking a Poop Barrel with a sharp object, like a needle, is a bad idea.
Person 1: How's everything rolling bro?
Person 2: Like a Poop Barrel on a downhill man.
