I don't know what a sandfooker is and I daren't try and guess. But I do know what a sandgroper is.
I don't know what a sandgroper is but I am immediately adding it to my vocabulary.
Disappointingly, if you call someone a sandgroper, you are accusing them of being a pioneer of the nineteenth century Australian gold rush. But they won't know that...
There was a miner forty niner...I didn't know that word. I rather like sandfumbler too.

Not in any of the 1000-odd ones recognised by Onelook.com. But then shedloads of your vocabulary fall into that category.
