Put it away, Luv.

That's what Britain's Advertising Standards Authority is telling Diesel after banning its new flasher-inspired campaign, the Daily Mail reports.

Diesel's "Be Stupid" campaign, which featured female models flashing their (mostly unseen) breasts at security cameras and snapping crotch shots of themselves, has been blasted by the ad watchdog for being indecent and antisocial, according to the paper.

Flashing? Antisocial? But that's how we met our last five boyfriends!

The fashion label reportedly claimed that the "nonexploitative" ads -- which ran the tagline "Smart May Have the Brains, but Stupid Has the Balls. Be Stupid, Diesel" -- "portrayed a very strong and unexpected image of femininity, aligning it with typically masculine themes." (Axe Body Spray, anyone?)

The brand also reportedly noted that the ads did not feature "any provocative nudity beyond the usual amounts shown in many swimwear, sportswear, or lingerie ads."

Still, the ASA isn't buying it.

In a ruling issued today, the agency argued that one ad was "likely to cause serious offense to many adults because it was clear that she was taking a photograph of her genitalia," while the other "was likely to cause serious or widespread offense because, although her breasts were only partially visible, the image showed her exposing herself to a surveillance camera."

"We considered that the image portrayed socially challenging actions that might be attractive to younger consumers who would be interested in the youthful and edgy fashion range and might encourage behavior that was antisocial or irresponsible," the ASA reportedly added.

As a result, the two images have been banned from running as public posters, according to the Daily Mail.

Back to the drawing board, guys! Guess you'll have to save the flashing for Mardi Gras?

Meanwhile, the ASA recently ruled in favor of Cheryl Cole's controversial L'Oreal ad.
