Aww. It's such a quirky and funny thought, imagine eating the rubble as an intimidation attempt, like, the guy just missed but is trying to turn it into a "that was intentional, I wanted you to know what I'm going to do to your BRAIN after I cave in your skull!"

This is the kind of stuff that makes a game memorable IMO. As a DM, even if you don't want to allow it for some reason, just go along with it. Fake a roll and have the opponent yell back "Bahahah I haven't even hit you yet and you're already getting ready to start shitting bricks?!"
