I used the terms prodydog and catlick on another thread with no censure. They were terms we used as kids in fun but if anyone was seriously offended I would have apologised and stopped. It is as much context as the terms themselves. Take the word 'Brit'. It can be a simple description of someone British or, in context, be derogatory. It is not beyond any of our wits to see how it is being used yet someone will undoubtedly take offence regardless of the intent.
