Someone has pissed rapper Trina off. TMZ reports Trina was in a Cooper City Walmart when she bumped into a woman, which, may have been by accident. Witnesses say Trina bumped into a woman in an aisle and the lady told Trina, "Watch out, you n****r bitch." Ouch! Did she have to call Trina names? Well that's when it definitely turned left and you hear on a video, Trina telling to the lady to call her that again. Police were called to the scene about people screaming at each other in the store. Trina decided against the police report, but she was escorted out of Walmart for safety measure. It's definitely crazy how people can just throw these words out there are freely over the most smallest of situations and/or mistakes.
