Cicadian

Cicadian: adjective. This word is only found in natural language in conjunction with 'rhythm' in the phrase 'cicadian rhythm'. This refers to a person's sleep-wake cycle, when it is completely in the control of stupid, bloody-annoying angry crickets that just won't shut up. People with a cicadian rhythm are known to wake up at godforsaken hours of the night, due to incessant buzzing and chirping. Psychologists are currently investigating the apparent correlation between increase in violence and a cicadian rhythm.
