Shazamposting refers to a diverse genre of internet memes centered around the DC Comics character Shazam, his transformation sequence, and the surrounding pop culture mysteries. While it gained mainstream traction with the release of the 2019 film starring Zachary Levi, a significant portion of the Shazamposting subculture revolves around the Mandela Effect regarding a non-existent 90s movie titled Shazaam starring Sinbad. In meme circles, it often involves shitposting about the character's lightning-fast transformation, using the 'SHAZAM!' shout as a punchline for sudden changes in status, power, or physical appearance. Whether it's ironic worship of the franchise or making fun of cinematic tropes, Shazamposting remains a staple of superhero fandom online.
