The clip's file metadata identifies it as coming from Programa Jurandir Mitoso, broadcast on Rádio Cidade AM 860 kHz in Fortaleza in April 2015. In Portuguese, a maior baixaria roughly means the greatest vulgarity or low behaviour, which explains why the phrase works as a judgement rather than a neutral sound effect. As a soundboard clip, it circulates mainly as a short reaction for Portuguese-speaking creators, who use it to label a moment as shameless, crude or scandalous without adding a longer commentary track.
