Rhyming slang - Butchers hook, meaning look

1) When someone is online on MSN but has selected "Appear Offline" As their status, so that they talk to only who they choose

2) When someone is deliberatly ignoring you, ie they look at you, you say Hi, and they turn away again and walk off.

Originally non-offensive - most use being proffesional in the medical career - meaning born to parents who are either not together or un-married.
