A.R.M is an acronym for American resistance movement. The American resistance movement is in essence a bunch of ex army soldiers and marine core rejects that seem to always find a reason to hate the government, every religion except christianity, every race except for white people, and democrats. Also they lack intelligence have many children, a wife whom they most likely rape repetitively, drink beer everyday except for sunday when they respect the lord by supporting there meth addictions while the leave there kids watching spongebob for hours on end. They enjoy drinking mountain dew, and beating and/or treating there women as maids instead of partners. Watch out for the ARM.
Dude my friend is in the ARM, he beats his wife n steals from her purse to buy meth, and mountain dew.
