That thing that you find in your closet after leaving a glass of milk in there for eight years. But it could also be the expression on a gay mans face when a naked woman jumps on his head, or how you find blue lint in your naval after you wore a white shirt for three days.
Ouch my niffum is bleeding.

You ate my niffum right off of my plate!!!

The wild niffums are loose.
