Mpreg, short for male pregnancy, is a long-standing trope that originated within fan fiction communities on platforms like LiveJournal and Archive of Our Own (AO3), often associated with the 'Omegaverse' subgenre. While it began as a niche interest in slash fiction and digital art on DeviantArt, it eventually crossed over into mainstream internet culture as a form of surreal or 'cursed' humor. Today, Mpreg memes are frequently used to satirize bizarre fanfiction clichés or as a hyperbolic way to describe feeling bloated after a large meal. The meme's longevity stems from its shock value, its deep roots in internet subcultures, and its frequent appearance in unexpected fandom contexts.
