The 'Oh Yeah Woo Yeah' meme features a low-frame-rate animation of a simple white character or bird-like creature performing a rhythmic, celebratory dance. It gained significant traction on social media platforms like Twitter and Tumblr as a low-effort yet highly infectious way to express pure joy or ironic enthusiasm. The phrase 'Oh Yeah Woo Yeah' serves as a rhythmic chant that accompanies the character's movements, often used to celebrate mundane victories or to mock overly enthusiastic reactions. Its popularity stems from its simplicity and the charmingly crude aesthetic of the character, making it a staple in shitposting and 'weird internet' communities.
