'fit as a butchers dog' has always meant 'healthy' around here, old people tend to use it to describe themselves - inevitably shortly before slightly stumbling off a kerb and shattering every bone in their legs.
'He turned around and said'I particularly like COME HERE AND FUCK OFF
It doesn't make a BIT of sense, but I use it all the time. Same as 'I'm not being funny but' (Before a perfectly reasonable statement) and 'How can you just stand there and...' (to anyone, even if they're seated).I love hearing "So I turned to her and said, I said "....." "
A lot of northern British phrases seem to involve 'shit' or 'arse'. If you're nervous, you 'could shit through the eye of a needle'. If you're angry, you've 'got your arse in your hand' of you've 'seen your arse'.
I feel like a psychologist could have a field day.
