Place it at the end of a rambling monologue, right after the longest claim, then follow it with a short laugh for contrast. Pair it with Oh My God Wow before the rant to set up the exaggeration, and with Nelson's Ha-Ha afterwards if you want it to turn into open mockery.

This is a very short spoken clip built around the words nobody cares, delivered in a flat, dismissive tone that lands in just over a second. It feels blunt, unbothered and faintly funny, the kind of deadpan brush-off that cuts a long story short without raising its voice. Use it when a reply needs attitude rather than an explanation.
