The part of the womans body which lies between the pussy and the breasts. Commonly called that because it is a waste of space and if it weren't there, then there'd just be tits and ass!
Noun - "I tell you man, if the waist weren't there we wouldn't have ta look after so much, and Vegas would be so much closer to Disneyland!"
