Sounds like a guest on Sean Hannity's radio show got just a little too worked up yesterday over the killing of Osama bin Laden. I first heard this live on WABC in New York yesterday. It may sound as if she is saying "we killed the sucker" as it went unedited. But I heard it replayed on another station and with the audio slowed down, sounds like a different consonant was used...
