Get lost; piss off.
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"
Jog on your
gait, ye blatherskate,
My name is
Maggie Lauder.
(Get on your way, you bletherer,
My name is Maggie Lauder.)
