Decider

[Luis Fok]

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.

[Merna]

1.) A person in a leadership role, usually of limited intelligence and lacking keen self-awareness, who stubbornly insists on making all the decisions that often end in abject failure with dire consequences for others.
2.) George W. Bushs description for himself, at a White House press briefing on April 19, 2006. Bush told reporters, I’m the decider, and I decide what’s best. And what’s best is for Don Rumsfeld to remain as the secretary of defense.”

[Greta]

A churlish and irresponsible individual, when responding to any and all criticism with all the moral and logical authority of a 4-year-old; might also express some elements of claivoyance.

[Britney]

A game, goal, point, etc. that settles a contest or series of contests.
