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.

Get the Grustomer mug.
Ka - A British slang word for good.

Originates from the English drink KA.

Must be said by spelling it out with your lips covering your teeth which should make it sound weird and you should elongate the A sound.
George: Jayz bruv look at this fat draw.
Reiss: OOOHH KAAAAA LA.
