Originally a campfire nursery rhyme, Baby Shark became an inescapable global phenomenon after the South Korean company Pinkfong released their version in 2016. It eventually became the most-viewed video in YouTube history, cementing its place in the cultural zeitgeist. In the world of memes, Baby Shark represents the ultimate earworm—a song so catchy it borders on psychological annoyance. Memes often focus on the exhaustion of parents hearing it for the thousandth time, its use as a lighthearted meta-joke about viral trends, or the sheer ubiquity of the 'doo doo doo' rhythm in modern pop culture.
