Place it right after the question in an edit, then follow it with Bruh for a reaction to the non-answer, or with Emotional Damage when the dodge backfires. Keep it as the punchline reply, not as background, so the question and the answer stay linked.

This clip is the spoken phrase 'I don't know', running for about sixteen seconds instead of a brief two-word reply. It feels evasive and awkward, like someone stalling while everyone waits for a real answer, and it works as a deadpan dodge when no answer will do. The extended length makes the uncertainty itself the point.
