Nine hysterical women 

An overwhelming and practical response from the fans to events in a TV series, book, film, etc.

The first nine hysterical women were Torchwood fans, who sent coffee and letters to the BBC protesting against the death of Ianto Jones. Over 900 people registered on one LiveJournal community alone.

Russell T Davies: "The 'controversy' over Ianto's death is just nine hysterical women."

Or:
If (character) dies this series, they'll have nine hysterical women on their hands.
