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?

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.)
