106 & Park debuted a new segment this week called "The Backroom," and 2 Chainz was the first artist to be featured on it. In the video above, 2 Chainz spits an exclusive freestyle over a grimacing beat. This is definitely reminiscent of the Rap City freestyle sessions from back in the day. Watch above, as Chainz proclaims to his competition, "While you suckin' like a vacuum, I'm 2 Chainz and I'm live in 'The Backroom.'"
