The chant grew out of Formula 1 fandom around Dutch driver Max Verstappen, whose dominance turned his name into a ready made singalong hook for fans online. Short clips of the tu tu tu du line spread through racing edits, social posts and reaction videos, where the simplicity of the melody made it easy to copy, remix and reuse. It remains popular because it signals support and celebration instantly, works without explanation for F1 followers, and can be dropped into wins, overtakes, gaming races or any moment presented as a Verstappen style victory.
