The humor comes from acting baffled by a very normal unit of measurement.

This sound is widely used online as a reaction meme tied to jokes about the metric system, especially posts exaggerating American unfamiliarity with kilometers. The exact original source of this specific clip is not reliably clear from the available facts, but the phrase spread through short-form videos, reposts and patriotic parody edits.
