A very short spoken clip built around the blunt retort you're not my dad, delivered with a defiant, unimpressed edge that makes the refusal land instantly. It feels cheeky and rebellious, like pushing back against an unwanted lecture with a single line, and it works best as a quick, dismissive answer rather than a long argument.
