Evil trickster gnomes that run around and cause any inconvenience to you while you are consuming alcohol.
Liquor Gnomes can be avoided by carrying around a personal gnome to act as a camouflage, as gnomes have no interest in harming their own kind.
Person 1: "What happened to you last night? You broke your glasses and then disappeared to go sing karaoke after we finished all of those beers."
Person 2: "The Liquor Gnomes got to me."
