Traveling down to the depths of tartarus, down the nine nocturnal levels of the underworld, beneath the dark one, in the basement of the devil himself, you'll find a small sack of salt. This is colloquially referred to as a Louch.
Boy 1: aye yoHercules was gucci, what'd you got in that sac?
Hercules: about five grams of Louch.

Loucheness
The quality of being a disreputable but somehow endearing person. A loveable scamp.
From French for "squinting", ultimately from Latin, for "blind in one eye" So, possibly it means to turn a blind eye to someones bad reputation.
