Place it at the very end of a clip as the final sign-off, after the last line lands. Pair it with Bruh for a dry exit, or put Meme before it to set up the joke, then let it close the scene.

This is a short spoken clip of a voice saying the Portuguese word for goodbye, 'tchau', in a bright, upbeat way that lasts just over five seconds. It feels light, cheeky and friendly, like a playful wave as someone walks out the door, and it works best as a quick, warm farewell rather than a serious goodbye.
