What happens when you have swamp ass and your shorts ride up in your asscrack. It makes your rectal area feel a bit wet and sloppy and makes you want to instinctively wipe your ass. People experiencing grimjock may walk in a strange fashion, due to the disgusting feeling it leaves in one's asshole. Mostly occurs in individuals who follow a sedentary lifestyle and/or are morbidly obese.
Person A: Yo, I got some mad grimjock right now. I feel so fucking gross, I gotta go wipe my ass and take a shower.
Person B: Try losing some weight, you fat fuck.
