The 'What The Fuck Is A Kilometer' meme is a satirical expression of extreme American patriotism and confusion toward the metric system. While the phrase has circulated in various forms, it gained massive popularity through a clip featuring Logan Paul, often edited with images of bald eagles, the American flag, and explosions. It is typically used to accompany videos of impressive feats in gaming or sports, implying that 'American' power is so great it transcends foreign measurements. The meme effectively pokes fun at the United States' refusal to adopt the metric system while simultaneously leaning into 'Merica' stereotypes.
