When somebody has offended you, or boyed you off, you should reply saying "par". It's similar in usage to allow, but you omit the pronoun, and this can only be used when somebody is offending you personally.
You: "Par. I'm safe with him, though."
The rise of casual crime in Par went relatively unnoticed by the inhabitants until an innocent man was beaten to death on Par Beach by four drunken thugs. Since then there has been a spate of beatings, graffiti and general vandalism.
One common sight in Par is the continual circling of irritatingly loud mopeds and stupidly modified cars around the one way system. This is due to a lack of things to do in Par.
At night, common sights include gangs of 15-year-olds pretending to be gangsters getting drunk on a single can of Stella between them, and girls of the same age looking like shop dummies that have been spray painted orange.
Mate: Um, let's not. I find Par's huge amounts of inbred crack dealers and schoolboys casually vandalising cars quite a deterrant.
Charlie: Ah, that's true! Let's go to Plymouth instead.
