God only knows what you would make of my South London accent then. As for taking the piss, well there are 2 meanings really. 1: Taking the mickey out of someone as already explained. 2: Not sure of the best way to word it but an example would be you have just spent 5 hours working your guts out and its home time then your boss comes in and asks you to do something that you know will take another 2 hours while he buggers off home. You would then say he is 'taking the piss'.
