A good word to use in the military when a soldier of a lower rank fails to notice your commands due to their stupidity.
Pvt - (stands around aimlessly)
Sgt - Fall in to the parade private!
Pvt - *Yawn* (still stands there, scratching his arse)
Sgt - FALL IN NOW! YOU HUMAN QUESTIONMARK!
Pvt - Sorry Sgt didnt hear you, got wax in me ears you see.
Good phrase for use in the Military to lower ranks.
Pvt: (wanders around aimlessly)
Sgt: What the hell are you doing private? Fall in...you human question mark.
