The Young Sheldon meme stems from the popular CBS sitcom 'Young Sheldon,' a prequel to 'The Big Bang Theory' that follows the childhood of the socially awkward prodigy Sheldon Cooper. On the internet, scenes of the young protagonist are frequently used to depict 'know-it-all' energy, condescending intellectualism, or overly logical responses to mundane situations. While the show started in 2017, it gained a massive second life on platforms like TikTok and Twitter through ironic edits and reaction images that highlight Sheldon’s unique, pedantic personality. It has become a staple for anyone wanting to deliver an 'um, actually' punchline with a recognizable face.
