Stupid Oatmeal

Oatmeal eaten by a person who you have great contempt for. Even their oatmeal is stupid. Variations include "dumb grabola," "moronic cereal," "silly porridge," and possibly "imbecilic cottage cheese" (though this one is disputed by many to be a real variant, due to the lack of an oatmeal synonym).

Student: Oh, this teacher is so annoying. She always comes into class 20 minutes late with her stupid oatmeal.
