A popular meme, often tagged using the squinty eyed pic of Futurama Fry. Used to check if something really is x or not, in a humorously stupid way.

From the movie, "Idiocracy". It is the name that the machine gave the main character, Private Joe Bauers when he was getting his UPC code tattooed on his arm. After that, he was called "Not Sure" throughout the movie.
Female Reporter: It started off boring and slow with Not Sure trying to bullshit everyone with a bunch of smart talk: 'Blah blah blah. You gotta believe me!' That part of the trial sucked! But then the Chief J. just went off. He said, 'Man, whatever! The guy's guilty as shit! We all know that.' And he sentenced his ass to one night of rehabilitation.

President Camacho: Number 1: We've got this guy Not Sure. Number 2: He's got a higher IQ than ANY MAN ALIVE. and Number 3: He's going to fix EVERYTHING.
