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?

A fart nugget accours when you are with a group of friends and you feel a little gas coming on. You feel very excited because you want to but on a good show for you friends. You push extremly hard and then, pooooop, you shit your pants with a hard turd. Luckly for you, you can make a swift move to 2 restroom before anyone notices becasue your ass wont we wet and brown, only brown. You should be able to clean you panties with a few sheets of Toile paper. If there is no brown left on your white panties, CONGRADULATIONS, you have succsefully ddroped a "Fart Nugget"
