There’s beef over a beach privacy breach. 

A brawl broke loose on Italy’s longstanding gender-segregated beach, Bagno Marino La Lanterna, known locally as Pedocin, this weekend, after a ballsy bombshell broke the abiding rule and joined her boyfriend on the boys-only side of the seashore. 

“You’re living in the Middle Ages,” the unnamed lady-rebel reportedly spat at beachgoers who berated her for traipsing onto the sands exclusively designated for dudes Saturday.

Pedocin, located in the northern Italian city of Trieste, was established in the early 1900s and is believed to be the last gender-split beach in Europe. The pebble-riddled hotspot, nestled along the Adriatic Sea, is divided by a 9-foot wall separating the guys from the gals and children under age 12. 

Women are free to sport skimpy swimsuits and go topless while sunbathing sans falling prey to the male gaze on their side of the beach, according to insiders. Men can talk shop and read the paper in paradise-like peace on their stretch of the land. To fraternize, the sexes are welcome to swim out to the buoys for watery mingling.

It’s a seemingly idyllic deal that locals have enjoyed for over a century — until, of course, this nonconformist came to town. 

“You’re a bunch of sexist oafs. This is a form of discrimination. Shame on you,” the wall-jumping woman, a tourist from Milan, allegedly yelled at another woman who politely asked her to refrain from sunbathing on the fellas’ beach. 

The beachgoer, said to be a mother in her 50s, was allegedly on the men’s side to help her husband take their disabled son to the restroom. 

Still, the irate anarchist reportedly labeled the special needs mom “sexist” and “backward” before “threateningly” approaching the woman with a raised hand, per Il Piccolo.

The men on the scene reportedly de-escalated the situation prior to the women coming to blows. A female beach worker, however, was shoved amid the fray. 

Before leaving Pedocin in a huff, the petty troublemaker and her beau allegedly demanded a full refund of their beach entry fee, a whopping €2.40 ($2.73). 

Critics across the internet virtually scolded the hellion for raising unnecessary hell at this otherwise happy hangout. 

“It’s true that [the rule seems] like the Middle Ages, but why force your own rules on a place that already has its own?” a confused commenter questioned on X. 

“People aren’t right in the head…,” another faultfinder wrote, in part, referring to the defiant diva’s outburst. “They aren’t right in the head.”

“Only stupid, arrogant, and ignorant people could behave like that!,” tweeted another. “It’s an ancient tradition and it must be respected; those two Milanese [people] have shown all their stupidity. Two morons.”
