The term 'Glup Shitto' originated from a September 2020 Tumblr post by user pixelated-boat, which poked fun at the intense excitement Star Wars fans feel when a character from obscure expanded-universe media makes a cameo. The name has since become a universal shorthand for any minor, background, or niche character that only 'true fans' recognize, sparking a wave of memes that highlight the absurdity of deep-lore obsession. It captures the specific joy of seeing a character with a ridiculous name appear on screen while general audiences remain completely baffled by the hype. Today, it is widely used across various fandoms to describe the 'literal who' characters that fans treat like superstars.
