What is the source of this "Vegas Girl" story going around? I've recently had multiple different guys confide in me they told their ex girlfriend a made-up story that they were "Going to go meet another girl in Las Vegas for a concert," in order to make their ex girlfriend jealous. Can somebody point me to the source of this story?

Is this something that they're getting off of a TV show or a movie, a greentext going around, or is this an actual redpill technique? Someone said it sounds like dread-game.
