Place it as the closing beat of a short reaction edit, after the setup line has landed and before the clip cuts away. Follow it with Oh My God Wow for the next reaction, or lead into it with Nelson's Ha-Ha before the payoff.

The clip is an eight-second Brazilian Portuguese voice shout stretching the word lacrou into a long, triumphant wail. It feels cheeky and over-the-top, like a victory lap delivered at full volume after a burn lands. It comes from Inutilismo, and the drawn-out delivery is what turns a simple slang win into a loud, playful celebration.
