A genre of music that is similar to grindcore, except there are no lyrics. Vocalists only belch throughout every song. There are both random burps and sequences of rhythmic burping. More complex forms of belchcore may develop soon, including belching to mathcore or to heavy metal.
Object 1: This soda just made me belch like 5 times in a row.
Object 2: You could totally join a belchcore band.
