The 'Slutty Waist' meme is a viral slang term and aesthetic trend that gained massive traction on platforms like Twitter and TikTok. It typically refers to a specific physical silhouette characterized by very broad shoulders and a disproportionately narrow waist, often described as 'snatched.' While the terminology is provocative, it is widely used within fandom communities—particularly anime and superhero circles—to praise the character designs of muscular men. It eventually crossed over into gym culture and fashion, where users post 'thirst traps' or character appreciation threads using the phrase to highlight an idealized V-taper physique.
