When a singer intentionally changes the way he phrases or sings his words, most prevalent in grunge music. (i.e. pronouncing "here" like "hurr") The worst case of grunge mouth has to be Scott Stapp of the band Creed. Sometimes a case of grungemouth can be so bad that it renders the person incoherent. Pearl Jam's "Yellow Ledbetter" is a good example. :D
Worst purveyors of grunge mouth are Creed, Pearl Jam, early Stone Temple Pilots, most recently heard with band Volbeat.
