In my defence I think that this comes from a subconscious desire to vet those I come into contact with for a decent sense of humour, which as far as I'm concerned is a must. I have very high standards you see and get a bit awkward around people without a well developed sense of irony. Well that's how I justify it to myself anyhow. Alternatively I can feign a mild form of tourettes to justify my loose lips. Then you can't hold it against me right? Who's the bad guy now huh? Certainly not me. I'm not the one discriminating against someone with a fictional disability.
Another one of my nicknames is The Wanker from Sri Lanka. I'm not sure where that one came from. There are a lot of mean people out there. (By the way this last bit was a test)
