A white woman in Florida went absolutely berserk after catching a black teen littering, berating him and his family with a racial slur, video shows.

The unidentified woman went off Saturday on 14-year-old Barry Henry outside a FedEx store in St. Petersburg, where the teen was dropping off some documents with his grandmother, the Tampa Bay Times reports.

Inside the store, the ninth-grader bought a pack of Extra gum and later dropped a wrapper outside, a piece of trash he intended to pick up, he told the newspaper.

That prompted a nearby “middle-aged” woman to erupt immediately, according to footage of the encounter posted by Henry’s sister.

“Nuh uh, don’t even act like that!” the woman screamed. “Pick it up! Pick it up! Find it! Get down on your knees and find it!”

Henry then turns away from the woman and laughs nervously toward the camera as the woman escalated her verbal assault, footage shows.

“No account little n—-r,” she continued. “That’s how you are. All y’all, no account f–king n—–s! Walk around here acting like something!”

The woman then directed her ire toward Henry’s cousin, who recorded a portion of the encounter, the Tampa Bay Times reports.

“Film me, f–ker!” she said. “Film me!”

Tykeshia Henry-Burch, the teen’s mother, said it was the first time he had been called the N-word in his life.

“It was so unbelievable to me,” she told the newspaper of the footage. “I was so hurt and just couldn’t believe she had said those things to my son. He’s only 14.”

Henry-Burch said her daughter posted the video on Facebook against her will, but acknowledged her reasoning to “heighten awareness” that racism still flourishes in the United States.

“Almost 2020 and we still are dealing with being spoken to in this manner over what exactly?” the post read. “A gum wrapper. Tasteless.”

The woman – dubbed online as “Pick It Up Peggy” – desperately needs counseling, Henry-Burch told WFLA.

“I would tell her she needs to seek help, she has serious issues,” she told the station. “She needs to watch what she says to people.”
