(adj.) Combination of the words "middle" and "delicious": food which is neither extraordinarily tasty nor truly awful, but simply common, average, or adequate-quality cuisine. Often filling and good enough to eat if you're hungry, but you'd pass it up for *real* food.
Most store-bought pizza isn't superb, just middlicious. Believe me, I've had worse delivered.
