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.
