Any unwanted chunky debris hanging within the recess of one's butt. Butt nuggets normally require a concentrated effort in order to remove them, such as but no limited to: heavy wiping with toilet paper, or hot water and soap.

An insult similar to calling someone a "turd" or a "piece of crap", usually someone who does or says something really stupid or annoying.
The little "butt nugget" across the street kept coming over to my car when I would drive up wanting to show me his new "cool" bike. (The kid was all of 6 years old, a pest and dorky!)
