Grunders 

Underwear worn more than a 24 hour period of time by either a male or female. Underwear become Grunders after they are worn more than 24 hours or they are soiled and stained from urinary or anal leakage. The hallmark of turning your undies in to Grunders are those that are accentuated by skids and skid marks and mud marks.

Leroy was so behind in his laundry that he ran out of underwear. He ended up wearing the same pair for over two days. He finally did a load of whites after dropping skid marks in his Grunders.
