A unit of measurement equaling one-one thousandth of an inch.
When trying to measure out a length to cut wood three feet long your buddy named Grant says, "Oh, that would be about 36,000 Grant-dicks long", making your buddies then ask, "So Grant, your saying your dick is only 1/1000th of an inch? Sucks to be you"
