underpants

Male underwear worn under a pair of trousers or pants. Many people, mostly in the south of England, believe that underpants and pants are the same thing, which clearly isn't possible.

underpants gnomes

A general term for short-ass freshmen (occasionally uperclassmen) who have yet to hit puberty and appear to be in the fourth grade (both in physical appearance, psychological development and writing ability). Usually have some strange/repulsive/childish personal habits (Ex: playing one-man football). Non-anime boobies are like kryptonite to them. Often carry airport bags in lieu of backpacks, believed to be full of stolen underpants (this cannot be confirmed due to their kung-fu grip ability), suspected to be a part of the shadowy and sinister "Phase 2". Reviled by all but the most desperate or demented fanboys and otaku. Sometimes abbreviated to UPGs.

Underpants Gnomes

The Underpants Gnomes are mystical creatures that bring you back all of your missing nugs at the most opportune times. Whether you lost your frosty green nuggets during a fumble in the car, or you lost your whole sack during a drunken rampage, the Gnomes are sure to bring back what is rightfully yours in due time. If they happen to give your pot to someone else, do not worry, for the Gnomes are fair and will reimburse you at a later time.
They dwell anywhere that you may have been smoking pot, but these honored creatures never show themselves. Regardless, they must be thanked and honored when they present gifts.

"I dropped a couple nugs on the ground right here and they just vanished! WTF!"
"Ah bummer bro, it was probably the Underpants Gnomes."

"Fuck yeah, check this loud loud I just found under my seat! Must've been the Gnomes."
