Bubblegrunge is an internet aesthetic and micro-genre that emerged as a fusion of the hyper-feminine, bright 'bubblegum' pop culture of the late 90s and early 2000s with the grittier, darker elements of 90s grunge. Characterized by pastel colors, glitter, and Sanrio-inspired imagery paired with messy hair, ripped tights, and heavy boots, the meme side of Bubblegrunge explores the juxtaposition of being 'soft' yet 'edgy.' It gained significant traction on platforms like Tumblr, Pinterest, and TikTok, where users create mood boards or fashion lookbooks. In meme culture, it is frequently used to describe a person’s personality—appearing sweet and colorful on the surface while harboring a chaotic, rebellious, or moody interior.
