Place it at the end of a metric joke, right after the number appears, then follow it with the Bruh sound for a deadpan beat before cutting to the next scene. If the joke needs a bigger reaction, lead into the Emotional Damage Meme sound instead of stacking both.
About this sound
This five-second clip is a single shouted line asking what a kilometer is, delivered in a loud, confrontational voice that treats the metric unit like an insult. It feels absurdly defiant and instantly funny, turning simple confusion into mock patriotic outrage. It spread online as a reaction sound for posts about kilometers, Celsius and other non-American measurements.
