Scrat

A slang term(most prominently in Leeds/West Yorkshire) for the recreational drug MCAT aka 'Mephedrone' - Originally a legal(yet VERY potent) high, which first started appearing in the UK around 2008, but by April 2010 it had become classified as an illegal substance in the UK. Other names for scrat include Meow Meow, Bubble, M-Smack, or if you're from London 'drone' The potency of Scrat has slowly declined over the years, however the smell it omits is very much as flavoursome as it was in the old days... sometimes a very stale 'pissy' kind of smell, that you got in the old fashioned public gents loos with yellow balls in the urinal! - never use your bank card when racking up a slug with your pals, as if the slightest molecule of Scrat gets in your purse or wallet then you can't get shut of the fucking pong and all your work colleagues and family will know you are a wreck head!
