This one kind of goes with the "How tight is too tight" thread:
we call a girl that works in our office Princess Cameltoe-cameltoe for obvious reasons and princess because she has one of those things that goes around your license plate that says princess. She is one nasty girl.
Also we call one of our friends Helpy McHelperson because he always likes to tell people that are on the dance floor when their cellphones that are strapped to their belts are ringing.
