a phrase chiefly used in northern England.

it is a contracted form of "it'll be reet", where "reet" means "alright" or "OK".

living your life according to "be reet" is the only way to find happiness in life.

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".
