Noun. The small, minute particles of shit that adhere to the inside of the toilet when you have a massive, explosive bowel movement. Thought to be derived from the word "Freckels", which describe similar markings on a persons face or body.
Last night, at about 11:30 pm, I got this terrible stomach cramp. I barely made it to the bathroom before my ass decided to explode without any concern for the surrounding enviornment. After about 15 minutes of a good "power-shit", I flushed the toilet but the feckels on the underside of the ring were still very evident.
