A man has posted a video entitled 'Blatant Racism in Cheektowaga NY' on YouTube that appears to show a stranger making bilious racist comments and calling him a "nasty f***ing n****r".
The altercation took place outside a Dollar General store in the US, with the man parked in his car and the woman on the phone nearby with her two young children.
"I have her on tape calling me racist comments, calling me a n****r," user IAMOYAB says at the video's opening.
"Racism alive and well. Amazing," he adds, before the woman replies: "Sure is. It's disgusting what black people got into."
It is not clear what started the argument, with the woman claiming the man "scared her children".
*Warning - video contains offensive language*
The man doesn't rise to her remarks, but calmly repeats his allegations.
"You called me a n****r," he says.
"I called you a n****r. You're a n****r. Nasty f***ing n****r," the woman shoots back.
She is then seen apparently on the phone to her husband, whom she asks to come down to the store to "f***ing kill" the man.
The person on the other end of the phone appears to ask why he is filming, to which she responds: "He wants to put it on YouTube, try and act hard coz' I called him a racist ignorant n****r."
It is not clear whether any arrests were made, though IAMOYAB says during the video that he "doesn't sue people" and seemed to be simply trying to capture the rant to demonstrate how racist language is still being used every day in America.
"This happened to me last Friday May 30th 2014," he wrote under the video. "I'm more upset that it was done in front of her children. They will have hate and have no idea where it came from."
