Skeletrix Island is a surreal, digital aesthetic and lore-driven meme associated with the underground rap scene, specifically popularized by artists like Nettspend and the 'Skeletrix' brand. The imagery often features low-fidelity, glitchy graphics of skeletons, tropical palm trees, and Y2K-inspired internet art, creating an eerie yet nostalgic atmosphere. It evolved from a producer tag and visual branding into a full-blown internet mythos where fans 'visit' the island through abstract video edits and surreal shitposts. The meme is primarily used to signal involvement in niche internet subcultures, combining elements of 'drainer' aesthetics with modern rap irony and experimental visual styles.
