Chronic pessimism of a particularly severe nature. Derived from opti-rectum-itis as follows:
opti: having to do with optics, visual or eyes
rectum: the innermost and center between the gluteus maximus, the primary source of shitstains and buttnuggets; butthole; fecal exit, excremental departure zone.
itis: an inflammatory disease
FACTS: When hyper-signals originating in the optical and rectal regions of the human anatomy cross at certain points and become snared and start to resonate at unusually high amplitudes, the associated neuro- transmitters merge and the combined signals release an evolutionary combination of fecal-optical gases which then propogate directly to the frontal cortex of the brain. When the fecal-optical gases settle, an unsuspecting victim will often become pissy, negative, impatient and, generally, will exhibit symtoms of being a total scumbag schmegma breath.. especially around trusted friends and family!
General Symtom: A shitty outlook on life.
