The Omnitrix timeout comes from Cartoon Network's Ben 10 franchise, specifically the Alien Force era that ran from 2008 to 2010. In the show, the Omnitrix lets Ben become an alien only briefly, then flashes red and beeps as he is forced back to human form at the worst possible moment. Clipped and shared on soundboards, the short alarm became a meme shorthand for expiring luck. Much like the Metal Gear alert, it marks the exact instant a hero's advantage collapses, landing with the cold finality of Fatality when a plan fails.
