Place it as the reveal at the end of a prank edit, after the setup has played out and before any reaction shots. Follow it with a shocked reaction, then a laughing reaction to close the scene, so the trick, the surprise and the payoff land in that order.

This is a short spoken Portuguese prank line, lasting about 4.6 seconds, in which a voice announces 'Enganei vocês' — 'I fooled you' — with a teasing, triumphant tone. It feels playful and mischievous, like the punchline to a joke that has just landed, and it works best when the listener has only just realised they were tricked.
