A boy group signed to P. Diddy's Bad Boy Records. Consists of five brothers: Dustin, Kelly, Patrick, Carnell, and Bryan. They currently reside in the crunk capitol of the world, Atlanta, Georgia. The guys can sing and, as Diddy himself said, "Dance they asses off." The name "B5" comes from their last name, Breeding. Oh, and they're pretty cute, too.

B5 S4 refers to a car manufactured by AUDI(VW) between 1997-2002.. It comes in a station wagon (Avant) or 4 door sedan equipped with a twin turbo V6.. It is an engineering masterpiece due to it's timeless Audi shape, Quattro all wheel drive system, and aftermarket upgrade potential.. This is one of the most expensive cars on the road to maintain; and owning one will ultimately turn you into a 2.7t master-mechanic..
