this means quite literally to smoke the weeed man. usually used in a kinda way that only pot heads look forward to sayin. hey any chance to smizzle the wizle is a great chance for anyone.
A long gangster word I translated to: For Sure My Nigger With My Other Nigger. Used as a general show off word with no actual productive meaning. Just like saying a random mix of words ans hoping it impresses others when you say it fast.
