The line comes from the 2014 comedy 22 Jump Street, where Channing Tatum as Greg Jenko says My Name Is Jeff in a strained voice during an undercover scene. Clips of the moment spread quickly on Vine and YouTube and became a standalone reaction meme. PewDiePie repeated the line in his videos, introducing it to a huge gaming audience and giving it a second life beyond the film. It remains popular because the phrase is instantly recognisable and works without any setup.
