Armies are the plural noun of arms. Derived from the
latin word Brachium meaning the upper segment of the arm or forelimb extending from the shoulder to the elbow.
Armies holds some of the larger upper body muscles and are particularly expanded in men as they have a high amount of testosterone which helps build muscle strength in order to flex on the ladies and get some
sweet puss. This serves the purpose of procreation and protecting ones
children during aggravated disputes against other males.
