gnat's ass

Very small measurement used by toolmakers & engineers, or roughly .0001 or one ten thousandth of an inch. Actual size may vary between shops, but always much less than a pussy hair. About one tenth of a skosh which is equal to approximately one nudge of the dial.

Note: When specified, generally regarded as smaller than the smallest one can measure or produce, since while most people intuitively understand that a gnat's ass is pretty small, few have actually bothered a gnat to measure one.

"Clearance is clearance, Clarance, but that die is only missing by a gnat's ass".

Beer Gnat

Those little annoying flies that are attracted to / gather around an open beer after it's been left out for a night. My only question is "Damn, where do they come from"

dick gnats

Obnoxious gnats that swarm around a male dog's dick during the warmer months. Entomologists theorize they are attracted to the salt contained in the piss crystals matted in the dog's dick fur.

You reckon the reason dogs lick their dicks is to get the dick gnats off their peter??
