Ratinho is the stage name of Brazilian presenter Carlos Massa, host of Programa do Ratinho, the long-running SBT variety show that began in 1998. The elongated call of his name echoes the show's loud studio introductions and audience energy. Clipped from television and shared online, the shout spread across Brazilian social media and messaging apps as a short meme audio. It remains popular because the delivery is instantly recognisable to Brazilian viewers, while the exaggerated tone still reads as a funny announcement even out of context.
