Grustomer 

British slang for someone who purchases or solicits the purchase of Crack and/or Heroin.

It originates from a dealer named Grey and his customers that were often sighted around.
So the word Grey and customer were blended together to make Grustomer.

Ironically the slang words for Crack and Heroin in England are White and Black or Light and Dark - In that order.

These colours mixed to make the colour grey.

Synonyms: Budgehead, Crackhead, Nitty, etc.

Max: Ew, there's bare grustomers about.
Carl: Yeah... Fuckin' nitty.

Grustler 

Someone who can one-up hustling. Like hustlers they get money, bitches and drugs but in a different way. They try to broaden all the topics and gain them at once. A grustler doesn't care about anyone but themselves and they tend to make friends just to use them for money or certain protection. They can persuade very easily. They strive for money in the most hustling of ways.

Grustler1: "I sell weed out of my candy store so people will buy weed and candy." two birds one stone.

Grustler2: "I pimp bitches that pimp bitches and each one of them sell drugs, so I'm just racking up money." Grustling at it's best.
