When you eat spicy wings and forget to wash your hands only to later finger your girlfriend, and the dried hot sauce burns your girl's muff so severely that she accuses you of cheating and giving her an STD. From "The League."

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.
