The 'Aesthetic Warning' meme emerged as a staple of internet subcultures like vaporwave, glitchcore, and weirdcore. Originally used as a genuine content warning for flashing lights or high-contrast visuals, it quickly evolved into a stylistic trope used to signal that a following image or video is heavily curated for a specific 'vibe.' Usually featuring yellow warning icons and glitch-style typography, the meme is often used ironically to introduce everything from highly edited anime clips to surrealist digital art. On platforms like TikTok and Tumblr, it serves as a meta-commentary on internet visual culture, framing the 'aesthetic' itself as something overwhelming or even dangerous to the uninitiated.
