The phrase comes from Russian, where ya maslinu poymal literally means I caught an olive, and it circulated online as a standalone voice meme rather than as a famous movie or game line. Short clips of the delivery were reposted on soundboards and in video edits, where the unfamiliar language for many viewers made the proud tone even funnier. It stayed in use because it works without context, turning any small catch, grab or lucky find into a joke about celebrating something completely minor.
