A word of greeting amongst typically, but not exclusively, male Chavs, Townies and Scally's. Derived from the mispronunciation of the word 'boy', it is often used multiple times in the same sentence. It is most commonly used in a friendly manner, although when the enevitable eruption of tension and/or violence occurs between members of the community(ies) to which it belongs, it will be replaced, ironically, with the word 'mate'.
Male 1: "Alright buy? What's 'appnin buy?"
Male 2: "'ere buy did you see the buy other day what smashed that window down KFC in town?"
Male 1: "fuckin' 'ell buy yeh what a nutter innit buy!"

Get the Buymug. When something's REALLY important. The tags "bold," "underline," and "italicize" begin with the letters BUI, hence the term. When someone using BBCode BUIs something, you know shit's about to go down.
