Some one worse than a tramp/hobo, looks like one too, lower than low!, they're snakey (2faced, even towards there mates, if they have any!) and kats for drugs (crets/will do anything to get hold of some, they need it as much as they need oxygen.)
nitty - can you tick me some weed i swear on my mums life i will pay you back tomorrow!?!?!
Dealer - no you said that last time and the time before that, and still no money from you!, christ how many mums do you have!?
nitty steals valubules from his friends and sells it to buy drugs!
nitty smells bad and looks a mess, hasn't had a bath since, well they've never heard of it!!
nitty shakes where they cret for drugs so much and cant stop moving.
