Fury From The Mother Fucking Sky - A sarcastic abbreviation (derived from the motto of 4th Brigade, 82nd Airborne Division) which is used in reference to the laziness, incompetence, and unadulterated ignorance of 4-82. This modified battlecry serves as a motto in itself to some soldiers of 4th Infantry Division saying, "Well, at least we can't do worse than they did."
I still can't believe one of their company commanders brought an unexploded IED (Improvised Explosive Device) into their headquarters to show it off. FFTMFS!!
