6. Butterfingers “Ya Mama” (2004)

Nastiest lyric: "By tomorrow night you will be hungover and sick/ And I'll be at my home with yo’ mama on my dick."

There is nothing OK about this song, but what do you expect from an Australian who calls himself Evil Eddie? “Yo’ mama’s on the top of my things to do list” made it to the top twenty Down Under in 2004, and if the dozens are about trying to piss someone off, these guys are definitely on the right track.
