Tralaleo comes from Tralalero Tralala, part of the Italian brainrot wave that spread on TikTok in early 2025. The character is an AI generated shark with three legs wearing blue sneakers, paired with a nonsense Italian chant that fans repeat phonetically. As the meme exploded, editors began cutting its sounds over phonk tracks, a style known for Memphis vocals, cowbell and distorted bass. This phonk version strips the chant back and leans on the beat, making it reusable for edits far beyond the original shark videos.
