pound sand up your ass 

A common expression in the Army during the 70's & 80's.
A phrase used by equals to tell each other off, used by superiors to shut up subordinates.
A method of dismissing a stupid person.
The only possible use when you find yourself with a stick,
a funnel, some lube and a bag of sand.
A polite way to say fuck off.

Worker: "Hey boss, why don't we shut this job done and call
it a day, I'm tired."
Boss: " How can you be tired? You haven't done a damn thing all day. Maybe you should stay home tomorrow and pound sand up your ass!"
