The modern use of based, as in how people may refer to themselves online in a political context, originates from African American slang in the 2000s. After it became a meme in 2010, the left started to refer to themselves as Based King or Based Queen online. Today the word is even used by the right, although ironically.
You forgot to put your pronouns. How will anyone know whether to call you based king, based queen, or based monarch?
