The TBH Creature, also widely known as the Autism Creature or the 'Yippee!' bug, first emerged on Twitter in 2021 as a simplistic drawing of a white, four-legged creature with massive, unblinking eyes. It quickly gained traction within the neurodivergent community on platforms like Tumblr and TikTok, where it was adopted as an unofficial mascot for autism due to its literal, expressionless face and 'flat affect.' The meme reached legendary status when paired with an audio clip of a German child screaming 'Yippee!' followed by a celebratory sound effect. Today, the creature is used to represent moments of pure joy, hyperfixation, or simply the feeling of existing in a sensory-overloaded world.
