someone who is largely obssesed with the classic rock band Led Zeppelin, similar to the word Metalhead

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.

When your girl gives you the best head ever, while the greatest fucking band ever plays in the pack, Led Zeppelin, and when the 'Rain Song' comes on, you blow your load all over her face, tits, and hair, making it rain.
