Trina's shopping trip to Walmart turned racial when another customer allegedly called her a racial slur.
Law enforcement sources told TMZ that witnesses who were there claim Trina bumped into another woman in an aisle and the lady told Trina, "Watch out, you n***** bitch."
Trina lost it, and her epic rant was caught on video. You hear Trina screaming at a white woman, "say it again you dirty-ass b*tch! I am a n***** b*tch. Say it again! I dare you to say it!"
Sources say cops didn't take a police report because Trina decided against it. Officers escorted her out of the store to her car for safety measure.
TMZ was told police did not speak with the woman who allegedly hurled the racial slur.
