Empty Threat: (Phrase) A threat with no real backing, usually just made for effect.

In Madonna Is A Stupid, Irrelevant Turd Who Tries Too Hard News part one billiondey, Madonna made a statement at a New Jersey stop on her "Sticky & Sweet" tour "banning" Sarah Palin from attending any of her concerts. Oooh.

She told the crowd: "Sarah Palin can't come to my party. Sarah Palin can't come to my show. It's nothing personal," before adding, "Here's the sound of Sarah Palin's husband's snowmobile when it won't start," followed by a loud screeching noise. (Source)

I'm sure the governor will be crushed... Because if there's one thing I see when I look at Sarah Palin, it's an inner gay man clawing his way to get out. Maybe Kathy Griffin or Liza Minelli will be a little less discriminating in who attends their performances.
