the illness contracted after one comes home from an anime convention, usually caused by lack of sleep, shitty diet and screaming/ shouting for three or more days straight.

specific conventions have different names for it. kitacon, for example, calls it kit-aids.
person 1: how was anime matsuri?

person 2: awesome! the concert was badass, but i think i got the dreaded con plague. D:
