I quite like "get to fuck"
I used to have a T-shirt that said "I'm drunk, and you're ugly, but tomorrow I'll be sober". Always fun to wear out.
I don't give a fuckin monkeys if you think your mohammed "im 'ard" bruce lee
Some classics in this thread!
When having a slaggin' match I like to use:
" You have a face like a bag of smashed crabs"
"You're a fucking knob gobbler"
" Yeah well your mother is a cum guzzler and your da's bent"
^or "She's got a fud like a burst wellie".
I once heard a bloke from Middlesbrough advising a fellow Scot to "Fuck off you porridge gobbling cunt". Haha!
