The 'Deep Into YouTube' phenomenon refers to the act of stumbling upon obscure, bizarre, or low-view count videos that feel like hidden relics of the internet. Popularized largely by the r/deepintoyoutube community, this trope captures the specific vibe of a late-night internet rabbit hole where content shifts from mainstream viral hits to experimental art, forgotten home videos, and inexplicable animations. The meme is typically used to represent the feeling of losing track of time and sanity while browsing, often depicting a user's progression from normal entertainment to the truly surreal. It serves as a tribute to the chaotic, uncurated side of video-sharing platforms that exists beneath the algorithm's surface.
