Place it at the end of a short argument clip, after the other person has finished speaking, so it acts as the closing reply. Pair it first with No No Wait Wait to show the argument building, then follow the insult with Damn to keep the joke going.

This is a short spoken Portuguese insult, 'Vá à merda,' delivered in a sharp, dismissive tone over about four seconds. It lands as an angry, fed-up rejection, the kind of retort that cuts a conversation off instead of inviting a reply. Its direct delivery makes it feel confrontational, rude and deliberately final.
