The term 'Dindu Nuffin' is a pejorative slang phrase that originated on internet imageboards like 4chan during the 2014 Ferguson unrest. It is a phonetic spelling of the phrase 'didn't do nothing,' often used to mock individuals who claim innocence in the face of criminal accusations. Over time, the phrase evolved into a controversial meme template featuring various characters or real-life figures. While primarily used in political and social commentary, it remains a highly debated and polarized part of internet culture, often associated with specific online subcultures and social media discussions regarding law enforcement and social justice.
