Spanish. To collapse, as el derrumbe de communismo. The cry “Derrumbe” usually follows the sound of a huge crash. It occurs when a large building collapses. There are many shells of such buildings through out Havana. These are always a good source of fun and excitement. Sort of like those who gather to watch fires or auto accidents I suppose. Not sure why we delight in seeing such bad miserable things, but we do.
