"According to exclusive data from custom adult content website Clips4Sale, searches for the term “Barbie” on the platform have risen nearly tenfold, or 984 percent, since January — a few weeks after the initial teaser trailer dropped in December 2022. There are more than 15,000 clips tagged 'Barbie' in the title or description, and most of the content falls into one of two categories: “bimbofication” or “doll fetish,” which were both introduced onto the platform in 2017....

'I’m seeing more and more girls bimbofy themselves,' says Kelly Pierce, an adult content creator who has been making bimbofication content since 2007, when she first entered the industry. She tells Rolling Stone that while a few years ago, customers seemed more interested in creators with “a more natural” look, the trend has turned toward creators who “look as Barbie as possible”: 'They want the Nineties to return, when girls were ultra-feminine,” she says. “That’s what [customers] usually say. They want the ultra-femme, ultra-stripper look: blonde, big boobs.'”

'Bimbofication,' however, is an entirely different phenomenon. The term refers to a fetish for turning an intelligent, self-sufficient person into little more than a hypersexualized, vacuous blow-up doll. On Clips4Sale, videos catering to the fetish typically have titles like 'Therapist turned me into sex-obsessed bimbo' or 'mindless fuck doll bimbo training.” Occasionally, there’s an element of hypnosis involved as well...:
