A Herm is a truly outrageous penis measurement of 9 inches. Named after the person who is white (and claimer of a 9 inch penis), he has been laughed at for this absurd claim. The unit "Herm" is abbreviated "HK". 1 HK = 9 inches or 7039 HK = 1 mile....a 9 inch penis...come on Herm...
"Dude my arm is about 3 Herms long!!"

"I just ran 7039 Herms!..im pooped!!"

Herm, no way does your penis measure up to be one Herm!
