Place it at the exact point a roast turns personal in your edit, after the offending line has played in full. For a back-and-forth insult sequence, lead with kann es sein dass du dumm bist for the setup question, then answer with this clip as the escalation.
About this sound
A 3.4-second French voice clip of a male bystander erupting with the insult “Je t’encule, petite merde” and further abuse, delivered in a rough, fast shout with no lead-in. It feels openly hostile and shocking, turning any moment confrontational in an instant. It comes from Terminator 2: Judgment Day.
