The 'Selfcest' meme is a trope that revolves around a character engaging in a relationship or intense interaction with a version of themselves, often through time travel, cloning, or alternate dimensions. While the term originated within fanfiction circles—most notably with characters like The Once-ler and Loki—it has evolved into a broader internet meta-joke about extreme narcissism or being one's own biggest fan. Meme formats like the 'Spider-Man Pointing at Spider-Man' or 'Obama Giving Obama a Medal' are frequently used to illustrate these concepts. It captures the humorous and sometimes absurd realization that the only person one truly relates to is themselves.
