The 'your mom' joke is one of the oldest insults in comedy, and 'a tua mãe' is its Portuguese incarnation, a staple of schoolyard banter in Portugal and Brazil for generations. Short spoken clips like this one live a second life on soundboards and in messaging apps, where they are fired off as instant reaction audios the moment someone sets themselves up. The 'feat. Tomás' credit suggests the voice belongs to a friend or creator whose delivery made the line worth saving. Its staying power comes from simplicity: everybody knows the joke, so the timing does all the work.
