A male teenager with serious behavioural problems, primarily being a tool or wanker.
The Teentool is easily recognisable by its apparal. Usually a track or shell suit, the trousers of which are tucked into the socks; a baseball cap worn at a jaunty angle and either bling or tat's or both.
The Teentool's habitats are shopping arcades and magistrates courts.
The teentool's language is very complex and is broadly unintelligable except for the expletives which are peppered throughtout any given period of noise making.
The Teentool has a variety of modes of transport, apart from running, these include BMX style bicycles, small trail bikes or small old cars which have been pimped beyond recognition.
I have struck him from my Christmas list as he has become such a Teentool. I saw him outside the Magistrates court yesterday, gurning like a safari park chimp.
