Top Definition
An annoying little (fictive) being that makes life especialy difficult for Croquet players as well as all life forms in general. The Gnatt is also very short tempered (see: hockey-temper) and can bite and claw any innocent passer-by to death. No gnatts have been properly documented, but they can resemble an angry lepricorn. Can also be used as a word for anything negative or as an insult.
Anything/Anyone small and annoying is a gnatt or simply just gnatt.
