The 'You're Gonna Turn Into a Goomba' meme stems from the 1993 live-action Super Mario Bros. film, specifically a scene where King Koopa, played by Dennis Hopper, threatens a character with de-evolution. In the movie, Goombas were depicted as massive, lizard-like creatures with tiny heads, a stark and often ridiculed departure from the small mushroom enemies in the video games. This bizarre aesthetic choice, combined with the dramatic delivery of the line, led to the phrase becoming a cult classic internet meme. It is frequently used as a mock threat, a reaction to someone acting strangely, or to highlight the absurdity of the 90s film's character designs. Modern usage often appears in shitposting circles or short-form video content where the audio is layered over weird or awkward transformations.
