Shark Pog draws on two familiar pieces of internet slang, the shark meme format and the pog reaction borrowed from streaming culture, where pog signals hype and disbelief. Rather than coming from a single famous scene, the sound spread as a shareable soundboard clip, passed around in meme edits, gaming videos and reaction posts. Its appeal is the mismatch between a sea predator and a very human, excited expression, which keeps it useful long after the first post as a shorthand for stunned excitement online.
