It's a Hot Boy$ reunion in 2 Chainz video "Used To".  Actually, 2 Chainz told Rap Up that he was trying to get that whole Hot Boys feel again. 

In New Orleans, 2 Chainz, Lil Wayne, Juvenile, Mannie Fresh, and Turk (B.G. is currently behind bars) turt up during his visit to the 7th Ward.

This is DEFINITELY a club banger.  It's like a part two 2013 to "Back That Thang Up" video.
