M.O.P., short for Mash-Out Posse, is an American hardcore hip hop duo. The duo, comprising Billy Danzenie and Lil' Fame, are known for their angry, aggressive delivery. Although they maintain a strong underground following, they had some minor mainstream success in the early 2000s with the songs "Ante Up" and "Cold As Ice". The group has frequently collaborated with DJ Premier. Fame sometimes goes under the production moniker Fizzy Womack, and has produced on several M.O.P. releases as well as three AZ albums, Cormega's Who Am I?, Termanology's Da Cameo King, Big Noyd's Illustrious and the St. Da Squad mixtape.
