op-ti-rec-tum-it-us, noun,
1. An ambiguious mental condition which manifests itself by outbursts of negative thinking and behaviours. Experts have hypothesized that
the condition peaks whenever neuro-transmitters from the optic nerve cross the path traveled by transmitters from the nerves of the anus or other rectal areas. The most commonly observed symptom is an obvious
disposition by the sufferer that includes a severely
excremental outlook (shitty-outlook) on life and living.
2. Negative thinking; hopelessness.
