McM (McMange) is a Gaming Clan/ team that is most active in the Rainbow Six Siege community.
Owned and created by McM Lennon and McM Michael, who started the clan by mistake but has grown ever since. The clan started with the name McMange but the abbreviation "McM" was adopted early on and is now the main way of identifying the clan.

Friend- "What do you think of McM?"
Me- "Best clan in the world, with the best R6 players (Lennon and Michael)"
