Stash: transitive verb : to store in a usually secret place for future use

From “The Shawl”: I got my growth earlier that some boys, and, one night when I was thirteen and Doris and Raymond and I were sitting around wishing for something besides the oatmeal and commodity canned milk I’d stashed so he couldn’t sell them, I heard him coming down the road.

Now I understand that the boy kept the oatmeal and commodity canned milk in secret place so that his father won’t sell them and they could eat later.
