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 or players, who often are excluded from the term "dub."
For the last time people, a dub = an eighth oz. of marijuana And a half dub is the same thing as a half eighth.
Kids these days have misinterpreted the term "dub" to mean twenty dollars. This is idiotic. Don't make this mistake with seasoned dealers. But teenagers are making this interpretation the norm.
"yo, get me a dub of weed at the store." (usually $60 worth for danks)
