PewDiePie, whose real name is Felix Kjellberg, built a large YouTube audience with energetic Let's Play videos, especially horror games where his loud reactions became a signature part of the format. Short clips of those screams were lifted, shared and remixed across YouTube, TikTok and soundboards, turning them into a reusable scream meme for creators who want instant panic without recording their own reaction. Because the sound is short, recognisable and easy to drop into an edit, it has stayed popular for reaction videos, gaming highlights and comedy memes.
