squirrel (third-person singular simple present squirrels, present participle squirreling, simple past and past participle squirreled)
with "away": To hoard in a hidden place, by analogy to squirrels' habit of hoarding nuts.
with "around": To move or search erratically, especially as if hurried or confused.
My mother warned me not to squirrel around in my dad's workshop.
This only works with acorns! And other organics. Not with money, which does not really grow. That much.
So, the squirrel didn't realize he was planting a tree. It won't make new acorns for a couple of years though. Generations, really. His greatgrandchildren may profit. But only in autumn.
Also, in debating: "a squirrel can also refer to an affirmative so obscure that there is no known negative against it. These cases are rare and will typically win the round for the affirmative team". (Wikipedia)
Squirrel more, I say. In the obscure way. Or plant a tree. Just don't expect fruits until you have (grand)children.
