Re: "pillow biting"
Hmm, never heard that phrase - I just read it as a reference to being shafted. Maybe I've just led a sheltered life. Then again, I didn't understand the whole American outrage at the KFC advert in Australia that had fain placating Windies supporters by giving them some KFC - I'd never heard about the whole Black, fried chicken stereotype.
I suppose some people just enjoy being offended and announcing it to the world.
