"Prostagma" is associated with Age of Mythology, the 2002 real-time strategy game by Ensemble Studios. In the game, Greek units say it as an acknowledgment, and that tiny voice line stuck with players long after release. It spread online through gameplay clips, remixes, and memes about repeatedly clicking units in old RTS games. The sound still gets reused because it is instantly recognizable to strategy fans, easy to loop, and perfect for jokes about orders, grinding, and micromanagement.
