The 'Cover Them Up, Slut' meme originates from a scene in the Showtime drama series 'The L Word,' featuring characters Bette Porter and Alice Pieszecki. In the scene, Bette jokingly insults Alice's outfit, leading to the iconic line that has since become a staple of internet sass. While it started as a niche reference within the LGBTQ+ community, the meme gained mainstream popularity on Twitter and TikTok as a humorous way to react to someone showing even the slightest bit of skin or acting 'thirstily.' It is widely used to mock fake modesty or to playfully tease friends about their provocative posts, often appearing in redraws featuring popular fictional characters.
