screw the nut

British army slang for work harder you bastards.
Used mainly by NCOs at an attempt to get soldiers to work harder or put in a better effort.
After a fair amount of time in the services a soldier will learn that this phrase really means, make it look like im working harder.

Corporal} boys screw the nut else this will get a bit cheeky....cunts.
