The line comes from the 2014 comedy 22 Jump Street, where Channing Tatum as Greg Jenko attempts a fake identity during an undercover scene and delivers the name in a high pitched voice. The moment was clipped and shared widely on Vine and YouTube in the mid 2010s, turning the three word phrase into a standalone reaction. It stayed popular because the delivery is instantly recognizable even without video, and creators still reuse it for introductions, usernames and identity jokes across social platforms and streams today.
