Coulter had told the Philander Smith College audience Thursday that more conservative justices were needed on the Supreme Court to change the current law on abortion. Stevens is one of the court's most liberal members.
"We need somebody to put rat poisoning in Justice Stevens' creme brulee," Coulter said. "That's just a joke, for you in the media."
Coulter has made a career of writing and lecturing on her strongly conservative views.
At one point during her address, which was part of a lecture series, some audience members booed when she cut off two questioners. "I'm not going to be lectured to," Coulter told one man in a raised voice.
She drew more boos when she said the crack cocaine problem "has pretty much gone away."
