When you feel the two extreme sides of an emotion and everything in between, Good/Evil, Love/Hate. Having four wives would lead to a wide spectrum of all these emotions.

Term used to describe two ends of a spectrum. Love/Hate. Good/Evil because if one has four wives they are bound to experience a wide range of emotions. Can also be used as "fuck you".

Noun, plural: Women who are only ever seen in their chelsea tractors.
Works best when pronounced in the 'Jonathon Woss' estuarine english style so it sounds like an Essex person trying to say 'four-wheel-drives'.
