Comes from a song by Juelz Santana of the diplomats rap group called "Let's Go" where he says "Hey ma if you give good brain, you'll get a
dipset chain." So therefor if a
girl gives good brain then you give her a
dipset chain(figuratively). There are also levels such as silver for good, gold for great, and platinum for amazing.
Shnow:Ayo Shnowie, I just gave that
girl a
dipset chain.
Shnowie:Oh forreal, was it platinum?
Shnow:Naw it was
gold at best.
