Pound Sand 

"The origin of the expression go pound sand is from a longer expression, not to know (have enough sense to) pound sand down a rathole. Filling rat holes with sand is menial work, and telling someone to pound sand down a hole is like telling them to go fly a kite. The expression dates to at least 1912 and is common in the midwestern United States."
