Place it at the exact cut where a character appears, then follow it with Bruh for the reaction and Emotional Damage when the entrance turns into a joke at their expense.

This is a short, deadpan spoken line lasting just over a second, delivered in a flat, matter-of-fact voice as if an impossible arrival needs no explanation. It feels abruptly funny and slightly surreal, turning an ordinary entrance into a joke about appearing from nowhere. The line comes from Filthy Frank vs Chin Chin.
