The 'This Man Isn't Black' meme originated from a viral reaction video where a speaker identifies someone's lack of cultural alignment based on a specific action or preference. It quickly evolved into a popular social media trope, used primarily as a humorous way to 'revoke' someone's cultural standing over trivial disagreements, such as food preferences, music tastes, or fashion choices. The template is widely used on platforms like Twitter and TikTok to highlight hilarious contradictions between a person's background and their unexpected or 'unseasoned' opinions, making it a staple of modern internet commentary.
