Acronym for 'Terrorizing The Streets', a short-lived chav
based in the middle-class North West London suburb of Ruislip, consisting of a dozen delinquent fifteen year-old boys thinking they're hard by prowling the Ruislip high street in their Burberry
caps on Friday nights, graffiting everything in sight. Will attempt to start a fight on any grounds, but are not to be taken seriously.
Crew member: "TTS, blad. Gimmeyerfone."
