I've always said, 'I am a selector, I am not defector' - the first few phrases in English I learned. I said I hate 'defector'; something defective about the people. It's a bad word.
People wince when something is in bad taste. They laugh when it's funny. If it's too dirty or wrong, they won't laugh. But if it's a big, dirty, smart, funny laugh, they love it.
