The 'Once You Go Black You Never Go Back' TikTok trend leverages the popular idiom to showcase a point of no return after trying something superior. While the phrase has deep-rooted origins in popular culture, its TikTok manifestation typically uses a slowed or bass-boosted audio clip—often a remix of Meek Mill's 'Going Bad'—to highlight a sudden obsession or aesthetic shift. Users apply the template to anything from dark-themed fashion and black coffee to specific fictional characters or hobby transitions. The meme's popularity stems from its rhythmic timing and the versatility of the punchline, allowing creators to subvert the original meaning with humorous, relatable, or niche context.
