The 'DEUUEAUGH' meme originates from the classic SpongeBob SquarePants episode 'Something Smells,' where SpongeBob's horrendous breath causes a blue fish named Tom to let out a visceral, guttural sound of disgust. First aired in 2000, the moment became a cornerstone of internet reaction culture due to the fish's hilariously distorted facial expression and the unique phonetics of the gagging noise. It is primarily used to signal intense repulsion, whether responding to a literal bad smell, a terrible take on social media, or a cringeworthy video. Over the years, the meme has evolved through high-quality remixes and YouTube poops, maintaining its status as the go-to template for expressing pure, unadulterated distaste.
