"Go Pound Salt"

PPl that are concerned about the "go pound salt" phrase are looking into it too deeply. It means to "Go get lost" which is a pointless thing to do, so you are basically saying to someone, "get out of here" in an angry sort of way. It is not as rude as "[F-word] off" as some might like to think, its old-fashioned talk by NYC-area types that are lost in old-fashioned ways. So with "get lost","pound salt", or "pound sand"....there is no origin or historical meaning to it, pounding sand would be a pointless way to spend your time, so after you have done something undesirable to someone else, they might tell you to "go pound salt". I feel like I have "pounded salt" wasting time writing this pointless paragraph. End transmission.
