This is a short voice clip of someone stretching out the Portuguese word for donkey into a long, exasperated "oh burrooooooh" that lasts just over seven seconds. The drawn-out delivery makes it feel mockingly weary, like a sigh aimed at a spectacularly silly remark, and the humor comes from how long the speaker holds the groan instead of snapping back quickly.
