First, what is an a$$-hat? I understand the a$$ but not the "hat" part.
Actually I have to confess I have absolutely no idea. Safe to assume it's not a good thing.
But then I'm not hip to the latest slang. I still don't understand why anyone would want to be a gangsta or pimp, or own something that had been somehow 'pimped out'; in my day (1980's... ancient history
) anything 'geek' was bad.
