Place it at the end of a clip where Lucas keeps talking, so it acts as the cut-off. Put No No Wait Wait just before it when he tries to interrupt again, then follow it with Oh My God Wow as the group's reaction.

This clip is a spoken shout in Portuguese, with one voice telling Lucas to shut up in a direct, fed-up tone. It lands as blunt and funny, the kind of exasperated interruption that cuts through a noisy chat and makes the room laugh. The line is aimed at one person, but it works whenever someone needs to be told to stop talking and let everyone get a word in.
