Donnie Wahlberg was so perturbed he tweeted about it. Boston magazine has written us up. CBS Boston blasted us for what they called a “blunder.” And the Boston Globe is officially “indignant.”

What did we do? In reporting on the new Wahlburgers restaurant in Palo Alto, we decided to highlight the East Coast dishes on the menu — haddock, fluffernutters and what-not. After all, we’ve got burger joints galore out here. So we headlined the piece: “California’s first Wahlburgers: How to eat like a Southie.”

Coronavirus: Is it safe to dine indoors? Bay Area restaurants say their survival depends on it Oops! Turns out that “Southie” usage is as grating to those residents as it is to us when out-of-staters refer to San Francisco as “Frisco” or confuse Silicon Valley’s San Jose with the capital of Costa Rica.

Wahlberg was quick to correct us.

The actor/co-owner tweeted: “Calling one ‘A Southie’ is akin to calling one ‘A Palo Alto.’ Wahlberg’s aren’t from Southie. We love Southie, our late fathers last residence was in Southie (rest his soul), but we’re from Dorchester. Which doesn’t make us Dorchesters. Hope this helps.”

Yes, Donnie, it does, although in all fairness Southie does sound like a person and not a place.

Other residents also tweeted their “outrage” over the gaffe, Spencer Buell of Boston magazine wrote. And the Boston Globe’s Jeremy C. Fox talked of the “indignities for Bostonians.” (Gee, you’d think we’d accused the Patriots of deflating footballs or something.)

Buell wrote, “So why do we need to be reminded that ‘Southie’ is a neighborhood and not a name for a person from that place? Because another publication has done it again, this time California’s Mercury News in the heart of Silicon Valley.” (OK, points to Buell for the correct tech location.)

Turns out the New York Times incorrectly used the phrase “a fierce Southie” in a profile this year. And even “The Simpsons” show has gotten it wrong, Buell wrote.

However, he did throw us a bone: “To give credit where it’s due, it does in fact include a note about the correct way to pronounce frappe (“frap,” it says).”

For the record, we’ve now corrected the Southie and Dorchester references in our story. The headline now reads, “How to eat like you come from Southie.”

And we’d be happy to make further amends to Wahlberg when he and his brothers come to Palo Alto to check out their new restaurant.

The first fraps are on me.
