I mean the kind of stars you just utterly loathe so much, you won't see their movies, or if they are in a movie, you just wish you could ignore them so they wouldn't detract from your enjoyment. Either through your general annoyance with them, or their utter lack of acting ability, or just that you find them generally phony or whatever.
