Without resorting to google?
I was made to feel a bit of an arse for not knowing what it was last night and wanted to know if my education had been lacking of if the guy was being a smug git. And yes, I know the guy was being a smug git for pointing out publicly that I didn't know, but I want to know if its something I should have paid more attention to at school be aware of.
AIBU to ask you if you've heard of it before? And have you?
