Programa do Ratinho is a long-running Brazilian variety and talk show on SBT hosted by Carlos Massa, known as Ratinho, famous for its loud humor, audience segments and exaggerated reactions alongside other catchphrases like cavalo. Uepa became one of the host's signature exclamations on the program and later circulated outside television as a standalone audio clip on soundboards, messaging apps and social media in Brazil. Its brevity and unmistakable delivery helped it survive as a reusable reaction sound, detached from full episodes and understood instantly by Brazilian internet users.
