Vai la, vai la comes from the matchday repertoire of Sao Paulo Futebol Clube, one of Brazil's biggest clubs, nicknamed Tricolor Paulista for its red, white and black colours. Supporters sing vai la de coracao to urge the team on and declare they will be champions, a sentiment echoed in the vamos ser campeao line tied to this clip. Shared by fans as a short soundboard audio, it spread through football edits, WhatsApp groups and social posts, where its instant recognisability makes it a badge of SPFC support.
