Bun B posted a video to his social media, where he alleged that a woman called them a "n*gger" before threatening to shoot his wife, Queenie.
Bun B livestreamed the aftermath of the incident.
"So the [drive-thru] line extended out into the street; she pulled up and was blowing [her horn] at us to move," Bun told an officer on video.
"We told her to wait, we're not moving yet. She told my wife she was gonna threaten to shoot my wife, then she got out the car and called my wife 'a stupid n*gger.' I have everything on video."
The woman also appeared to be livestreaming the incident. They later drove to a local Walgreens where they spotted the same car, when Queenie rolled up on her and confronted her.
Queen asks her several times whether she is "still that n*gger," but the woman is quiet and walks away from her without uttering a single word.
