Chris Brown Diss Rihanna:"Theraflu" & "Mercy" (Freestyle)

Chris Brown unleash some killer bars on his "Theraflu" and "Mercy" freestyles. He even diss his former girl Rihanna, who has been trying publicly to build a relationship with him. Chris unfortunately has a chick, and he rolling with her. So I'm thinking he telling RiRi to move on, by dissing her. And I guess she has by unfollowing him on twitter, and he did the same. Just a couple days ago she wished him Happy Birthday, and they even did guess spots on each other records.
