Somerville’s Dragon Pizza owner and Barstool’s Dave Portnoy trade ‘F’ bombs, flip each other off in Davis Square

People all over the internet have been introduced to Somerville’s Dragon Pizza after its owner ripped into Barstool’s Dave Portnoy, and the pair exchanged “F” bombs and flipped each other off in a viral video.

The fiery interaction between the owner of Dragon Pizza in Davis Square and Portnoy has led to a spike of Yelp comments for Dragon Pizza — and an “Unusual Activity Alert” notice on the eatery’s Yelp page.

During one of Portnoy’s recent pizza reviews in Davis Square, Dragon Pizza owner Charlie Redd stepped outside his establishment and approached Portnoy on the Elm Street sidewalk.

“Dave, enjoy your pizza as any customer, but I don’t appreciate what you do, coming in and judging a business with one bite,” Redd told Portnoy.

“Well, we do more,” Portnoy responded.

“I hope you enjoy your pizza, but I don’t appreciate what you do to small businesses,” Redd said before walking back into Dragon Pizza.

“I’ve actually helped so many small businesses,” Portnoy said, adding that he raised $50 million for small businesses.

Then a minute later, Redd returns to the sidewalk, telling Portnoy to leave.

“Move on. Don’t stand in front of my business,” the owner said.

Portnoy quickly responded, “Let me be clear: (Expletive) you.”

“Let me be clear: Get the (expletive) out in front of my business,” Redd said back to Portnoy.

They then continued to trade a bunch of expletives and flip each other off.
