When something awful happens, people tend to pay attention to the awful thing, especially the victims. This is unacceptable to the Attention Shrieker who must be the center of attention at all times.

FEY AS PALIN: "So we ask reporters and commentators, stop using words that diminish us, like 'pretty,' 'attractive,' 'beautiful.'"
POEHLER AS CLINTON: "'Harpy,' 'shrew' and 'boner shrinker.'"
