Matheus Cunha, 27, gave the Seleção Brasileira its first goal against Haiti in the group stage of the Copa do Mundo Fifa 2026, then turned straight to his trademark celebration. It was the kind of finish that travels fast: one live match moment, one familiar move, and a trend already primed to catch it.
That is why M Cunha is being searched now. A TikTok trend has been spreading for weeks around characteristic celebrations from some of Brazil's best-known players, set to the song Brasil com S by DJ M4IA. The versions circulating online have leaned on names people already know, including Neymar, Vini Jr. and Raphinha, which helped the clips move from fan edits into something much larger.
The appeal of the format is simple. It takes a player, a signature celebration and a song, then repeats the formula until it feels like a shared language. In Cunha's case, the celebration was described only as his trademark move, which is enough to connect him to the trend even without a frame-by-frame breakdown of the gesture itself. The same logic explains why the TikTok clips can fold in Éder Militão, even though he is not in the Copa do Mundo Fifa 2026: one version uses him making the letter T with his arms, a reference to Tainá Militão that keeps the trend tied to personal markers rather than match data.
That friction matters because it shows how quickly a football moment can be absorbed into social media and reshaped beyond the field. Cunha's goal was the real event; the TikTok versions are the echo. What comes next is not another official update but whether the celebration trend keeps living off Brazil's World Cup moments or moves on to the next player who gives it a fresh copy to imitate.
