Place it at the opening of a short scene about a blocked entry or a petty rule, then follow it with Oi Meu Chapa for a friendly greeting that turns awkward, and finish with Ai Que Burro when the other person's excuse falls apart.
Sobre este sonido
This 3.5-second voice clip catches Severino, the tired doorman from Zorra Total, beginning his line 'isso é uma' in a flat, weary tone before it cuts off. It feels funny and knowing, like the start of a complaint you can predict, and it works for listeners who recognise the character's fed-up manner. The line comes from the Brazilian sketch show Zorra Total, where Paulo Silvino played Severino.
