The name imitates the sound of the sauce bubbling away as the pasta cooks in it — the dish is essentially named after the noise the pot makes.
Chunks of hand-broken spaghetti or other short pasta simmer directly in a rich tomato-and-meat sauce with onions, warming spices and often chickpeas, absorbing the liquid until the pasta turns thick and stew-like rather than being boiled and drained.
