I read an interview with Impaled Nazarene, who during one concert in Portugal got shit thrown at them, like broken beer bottles and stuff, the audience apparently totally hated them, so after a while one member who happened to know portuguese started insulting the audience in their native language which just riled them up even more, but IN made damn sure to finish their set, then bloody and bruised all over their body they even came back for encores, naked, then started chasing around members of the audience with broken beer bottles and asking them if they wanted to die.
