Other definitions of "doofus" lack the depth and degree of the term. A "doofus" is someone whose face jiggles like Richard Nixon when he falsely claims, "I am not a crook." Nixon was a darkside doofus. On the other hand Terrell Owens is a lightweight doofus. Not only does he rattle on like a moron, but his classic "face hanging out in front of his skull" is classic proof of Doofusism. George Bush would be a doofus if he wasn't such a Republican Peckerwood. The state of Republican Peckerwood inevitably leaves its host a drooling idiot. Look at Dick Cheney, for a strong example of lame-ass, senile yet psychotic Doofusism. In his last V.P. debate he starred in the role lame-ass doofus by laying across the podium like a too-pregnant wart-hog.
President Obama is something of a doofus, himself. He's a heroic doofus. He proves a doofus can be very intelligent and still be a doofus. He can outsmart the bad guys, save the planet and due to his glowing smile and Martian ears still be a "a face hanging out in front of his skull," doofus.
