The “Lizard Lizard Lizard” sound comes from the post-credit scene of Pixar’s movie Elio, where an alien character repeatedly shouts the phrase in a bizarre and funny way. Its quirky repetition quickly caught on as a meme sound on TikTok and other social platforms. Creators often use it in videos featuring weird, unexpected, or reptile-related moments. The sound has become a symbol for absurd humor and chaotic energy online.
