The word dub in recent years has taken on several different meanings. In the cocaine trafficking underworld, a dub is the street term for a bag worth $20 dollars. When referring to car rims, dub simply implies a minimum radius of 20".
When used in the musical context of a dj discussion, a dub is short for a dubplate, which is an acetate pressing of a record; although it is used in a loose sense and normally means 'an unreleased track'. However from a producer's standpoint dubbing can mean anything from adding sound, copying sounds, or omitting sounds from a recording.
