This is a short German voice line from Age of Empires, lasting about 1.6 seconds, in which a speaker tells people to build something already. The delivery feels impatient and exasperated, like a teammate losing patience during a match, which makes it funny rather than angry. It works as a quick nudge when someone needs a push to get building.
