Martidom means: Call of Duty4 Modern Warfare: A single grenade can be dropped after being killed to attempt to eliminate all nearby enemies. However, this word is not real. Call of Duty players insist that “Martyrdom”, as pronounced, is “Martidom”. They are wrong. It is actually “MARTER-DUM” and not “MARTYDOM”. (in Community Dictionary, added by Sylvia Love)
