The chant comes from 'Passinho do Volante,' the 2012 Brazilian funk hit by MC Federado e os Leleks built around the 'ah, lelek lek lek lek' hook. The track went viral in Brazil after footballer Neymar and other players danced to it, helping the refrain move from parties and terraces into YouTube edits and gaming streams. As a standalone soundboard clip, only the hook survives, which makes it portable for jokes far from the original song. Its dance association is why creators still reach for it for wins, moves and mock celebrations.
