When your thighs get unnaturally cold from holding a cold beverage between your legs.A change of bodily position and/or drink location are key in noticing this phenomenon.
After holding my soda in my lap driving to work, I got wicked pop crotch when I finally got out of my car.
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!
