I like the presentation of the entry and general idea of the mouth in the chest. It sparks imagination.
However, I would welcome something more advanced or innovative than flipping a coin. Using the die could introduce hunger cooldown in hours, plus modifier equal to the size of the meal or something. That could push the bearer of the chest-mouth into neverending hunt for food (real or metaphorical) with different windows in time during which they could feel full.
Yeah, constrained by the 36 word limit, and the self-imposed 3 words per line really constrained what I was doing with this. For me, the important part of having it be a coin flip is that whatever you are trying to stuff into yourself to sate the hole doesn't actually matter. At best, you only get a little bit of relief before it starts again. This is the part that really more ties it to the metaphorical representation of being stuck in a spiral of grief or depression.
