When you put a look up on your face when you smell some piss then whave your arms around like a bird while bobbing up and down, and continually wipe sweat from face in an exxagerated manner. Usually performed while on ecstasy.

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.
