PSL in an acronym used widely in the incelosphere for three consecutive forums that overlapped in userbase and prominent forum members: Puahate.com, Sluthate.com, and Lookism.net. All three forums were well known for their trolling atmosphere and lookist philosophy. None of these forums had/have sub-forums which self-identified as incel subforums, although the term was widely used in the “Shitty Advice” section of PUAhate, which was the most visited sub-forum the last few years of the site. Although the forums had origins in exclusive pick-up-artistry criticism, after the Elliot Rodger shooting, it morphed into a place to almost exclusively talk about how to improve ones looks to get dates on online dating. Lookism.net broke tradition a bit by self-identifying as an incel forum sorta around 2017, as well as becoming more sympathetic to pick-up-artistry.
