One of those great, frequently relevant one-liners. Now hijacked by chavs, making it sound less impressive than when it was only quoted by those who'd actually seen the movie.
British slang, wrongly believed by many to originate from the 2004 Nick Love film "The Football Factory".
The expression, however, has a far longer history - dating back in Scotland to at least the 1640s, when it appears in Francis Semphill's popular song "Maggie Lauder"
My name is Maggie Lauder.
(Get on your way, you bletherer,
My name is Maggie Lauder.)
