Shrader

A term used for a professor of mathematics that is (in general) a piece of shit that does not care for you, your grades, or your future. Unwilling to work with you for your grades, and always gives the hardest, worst, tests. This denizen of Hell can be encountered at schools all over the state of Georgia. Legend has it that he was once contained by the SCP Foundation, but broke containment due to his reality-warping effects and abilities. Keep your distance. If encountered, you ought to drop any classes he teaches for if you do not and you fail it is said that you will spend an eternity in servitude to him in his basement.
