Chupa, meaning suck it, is a long-running taunt in Brazilian football aimed here at São Paulo club Palmeiras, most pointedly by rivals Corinthians in the Derby Paulista. Smooth Operator was a 1984 hit for British band Sade, known for its smooth jazz-pop feel. Online editors combined the crude stadium chant with that polished track, and the full version circulated on Brazilian social media and messaging apps as a ready-made reaction whenever Palmeiras slipped up, giving rival fans a smug soundtrack that outlasted a single match or season.
