A decider is someone who makes decisions on issues using a lack of judgment and intelligence. Typically a decider has a propensity of sticking his head up his ass. He usually lets even more idiotic people make the actual decisions for him.

Apparently, The Decider is George W. Bush.
"I hear the voices, and I read the front page, and I know the speculation. But I'm the decider, and I decide what is best."
