Bust is the plain, everyday word for breaking something, and bust-up keeps the noise of it. Picture something that had been holding together — two people, a band, a quiet meeting — and then the moment it goes, loudly enough that everyone nearby turns round. Sometimes what breaks is only the peace of an afternoon, and you get a shouting row that is over by Wednesday. Sometimes what breaks is the relationship itself, and it does not go back together. Same crack, different depth.
