Slow-in-the-minds
"Slow-in-the-minds" and "slow minded" are CWC-isms that refer to mentally retarded, crazy, and/or generally stupid people. (Other than Chris himself, of course.) The term was first seen in Chris's school project "A Week With Christian Chandler."
"Slow-in-the-minds" hits a fine trifecta of points. One, it displays Chris's arrogance, seeing as how it applies to so many classes of people, all of whom he considers "slower" than he. Two, it shows Chris's lip-service attention to fitting in to society, since it's a piss-poor euphemism on its own and even worse when used in a school project. Three, there's a delicious irony in Chris decrying students who are "slow in the mind", even though his own mental aptitude is dubious.
In a number of responses from the Mailbag, Chris has explained that he finds the mentally handicapped (especially those who also have physical deformities) creepy, and likens them to zombies.[1][2] Chris's bigotry extends to his fellow autistics — he speaks in cruel and derisive terms about the various speech and physical problems that are thrust upon these innocent individuals, whereas he (as a self-proclaimed "high-functioning" autistic) is pure and clean. He barely seems to consider "lower-functioning" autistics human.
