Place it just after the swear in your edit, as the on-screen callout, then follow with Bruh for the group's disbelief and Game Show Buzzer as the penalty sound. That order turns one slip into a short running gag, with each reaction landing after the last.
About this sound
This is a short spoken meme clip, just under six seconds long, built around the line 'no more saying cuss words guys' delivered like a firm group warning. It feels playful and a little awkward, like being caught mid-swear by a friend who wants the chat cleaned up. The direct delivery makes the scolding land as a joke rather than a lecture.
