The 'Bitches Don't Know' meme, often followed by the phrase 'bout my [X],' originated from a 2006 MySpace photo featuring a young man looking smugly at the camera while wearing a hoodie. The phrase itself is believed to have roots in early internet imageboard culture, particularly 4chan, where it was used to mock individuals who felt superior due to their knowledge of obscure or trivial topics. Over the years, the template has evolved into a versatile tool for self-deprecating humor or genuine pride in a niche hobby. It perfectly captures that specific feeling of holding a secret piece of information or a skill that most people around you wouldn't understand or appreciate, making it a staple of internet culture for nearly two decades.
