The line comes from Rick and Morty, the Adult Swim animated series that premiered in 2013, where the cynical scientist Rick habitually shuts down his grandson Morty's earnest outbursts. In the scene, Morty is marveling at a stranger and rambling about how much the guy has going on before Rick cuts him off cold. The exchange became a stock meme audio because that exact rhythm, hype followed by a deadpan kill, fits almost any over-the-top setup, and it now circulates widely on soundboards and short-form video as the go-to clip for shutting someone down.
