Italian brainrot grew on TikTok in early 2025 around AI generated animal characters given long, rhyming Italian style names and dramatic voiceovers. Songs collecting the most popular names quickly followed, turning characters such as Tralalero Tralala, a shark in sneakers, and Orcalero Orcala, an orca in sneakers, into a single chantable hook. Clips spread through edits, rankings and remixes, with viewers repeating the names even without understanding them. The format remains popular because the rhythm is catchy, the characters are instantly recognisable, and new names can be added endlessly.
