What you find in your pants after an especially grievous fart.  Unexpected, surprising.  Can be used to describe an undesirable person.
Whew!  Whatta stench!  Did you check your drawers for a fartnugget?  or: Did you just drop a fartnugget?

Get the fartnuggetmug. Term used to refer to someone who insulted you with a greater knowledge of a fandom. Coined 5/28/14 in a Silmarillion fandom wank. (If the fartnugget in question is in a Tolkien fandom, "Taniquetil elitist" is an acceptable synonym.)
