A white person, usually in reference to a male. "Dub" is slang for "W," as in "White." At times, used in a pejorative sense, such as when a girl of another ethnicity appears to be favoring white males over her own kind. Note that in such instances, the target of the ill will usually is not the white male so much as the female. Shortening of "GWG," or "G dub G," meaning "goofy white guy," as these are inevitably the kind that said ethnic girls favor, as opposed to pimpin'
white guys or true ballers
, who often are excluded from the term "dub."
