About this sound
This is a short French spoken line lasting about two seconds, delivered in a dry, matter-of-fact voice that turns a small victory into a technicality. It feels wry and teasing, like a friendly correction that takes the shine off a boast without starting an argument. The line comes from The Lord of the Rings, where one impressive feat is counted as a single point.
