What’s your favourite insult?

I don’t know why or when it started but I seem to regularly use the insult ‘C0cksmith’ at people who annoy me these days. Just out of interest, what’s your favourite insult – I don’t mind if it’s one word or a beautifully crafted insult along the lines of Blackadder. Stick ‘em in the comments below.

C0cksmith.
