DEF-Bananas is a rapper/producer group hailing from Cherry Hill, New Jersey calling themselves a "three headed monster" (as their group consists of three people) they remind me of an underground 07-08 rap group (which isn't a bad thing).
The song is a play on the Barton Brands drink 99 Bananas, though it's more of one of those roll call tracks that show off lyrical talent than a song that talks about drinking habits.
