I'll tell thee that f'nowt
A cursed Yorkshire yell that comes out when you're annoyed and ready to punch someone.
She shouted, 'I'll tell thee that f'nowt!' after he took the last chip.
He yelled, 'I'll tell thee that f'nowt!' because the dog ate his homework.
He said, 'I'll tell thee that f'nowt!' right in the middle of the grocery store.
