Place it right at the cut where the person first appears on screen, after a quiet build-up shot. Follow it with a crowd cheer like the yaaaaaaaay cheer or a short laugh track reaction to sell the mock celebration, then return to normal dialogue.
About this sound
This is a short two-second voice clip of someone announcing in Portuguese that Sao Judas Tadeu has arrived, turning a saint's name into a grand entrance line. It feels funny and over the top, like a mock-serious celebration for an ordinary arrival, which is why it lands as a playful interruption rather than a solemn religious moment.
