O.T. Genasis -- I'm in Love with the Dough-Dough (TMZ TV)

It wasn't enough for “CoCo” rapper O.T. Genasis to flash us a giant wad of cash in his pocket -- he also popped the trunk of his SUV to reveal racks and racks of cash ... stacked and stacked in his ride!!

It's easily one of the most baller -- and yet, ill-advised -- moves we've ever seen a rapper make. And we've seen a lot.
