the feeling u get after consuming way too much coffee. u can no longer trust a fart at risk u might shart, and when u use the restroom, the liquidy excrement looks and smells like a very dark roast coffee. Often leading to an itchy & burning ass.
After several cups of coffee, Mike was returning to the restroom every few minutes; it was quite obvious to his coworkers he had a case of coffee ass.
