So, it's complicated. Not that you have the wrong idea in summary.
The guy who coined it (I have no idea why I have cyberstalked him for 9 years since I do find him kind of repugnant) meant quite literally "socially acceptable" lewdness. Socially acceptable to whom? Stereotypical game journalists and their sycophants, who have arbitrary (but consistently insufferable) criteria for what they will consider good taste in fanservice, as a weak defense to their constant attacks on actually good fanservice.
Hence, it's not truly generalizable to purely objective principles. But he does hate "reddit sexuality" (dominant/muscular w*man and all that), and of course absolutely hates that of the large spectrum of Internet leftoid cliques that hold a belief that you are morally obligated to find whatever pedestrians think is hideous to be beautiful.
For instance, he included Cammy's SF6 stretch pose in the mix, because he doesn't like it and game journos did (yes, it's just that important as a factor; also, he has a beef with Capcom for dumbing down Monster Hunter and is willing to be brazenly hypocritical or contrarian on lots of topics, because he's a bored NEET who picks Internet fights), whereas most people who accept the term would not, because nah that's pretty hot.

One gag he does now and then that I find amusing is to say "this wasn't me btw" to "South Australia Man" news items.
