settle someone's hash, to

To subdue; to get rid of someone or something. The “hash” in question is the mess that has been made of things. The term has been around since at least 1800. “We therefore mean to make a dash/To settle fighting Europe’s hash,” wrote T. G. Fessenden (Pills Political, 1809). Settling someone’s hash is not quite the same as making mincemeat of someone, despite the superficial similarity (both involve chopped meat). The latter implies complete demolition, i.e., chopping up.
