When someone has a raunchy ass fart (preferably warm and must be odor filled), cups their hand over their ass, and catchs this bundle of joy. Your next move takes precise timing as you only have seconds to deliver this devastating smell by cupping your hand over the victims nose and/or mouth while stating "Can of Poop!"

A turd so large in diameter that it feels like it's coming out of you the size of a beverage can of the 12-oz variety. It usually looks pretty big too and don't feel too great either!
The day after I ate that whole XL-Pizza with Double Extra Cheese, I was taking a dump when I thought my brown-eye was gonna rip open from the size of the turd I was trying expel. It felt like someone had shoved a pop can up my ass and it was kinda stuck there. When the marathon session was over I looked into the toilet and saw the monster I had created. Lesson learned. I never wanna make a Pop Can Poop again!
