This sound is associated with Shrek, the green ogre from DreamWorks' Shrek film series, which began in 2001. Roaring and yelling clips from the movies have stayed popular online because Shrek is instantly recognizable and widely used in ironic internet humor. Short Shrek audio moments get reused in meme compilations, gaming edits, and reaction posts where creators want a loud, familiar burst of comic intimidation. Its staying power comes from the character's huge meme status and the contrast between a fierce roar and a silly context.
