Top Definition
(n.) A mental disorder similar to insomnia. Wikomnia causes the victim to forgo the prudent option of sleep in lieu of endlessly browsing Wikipedia articles well into the night/morning. Patients who suffer from Wikomnia frequently show signs of always knowing a random factual tidbit of information to fit into every conversation regardless of the topic and waking up at dinner time without having completed any useful work the night before.
Jon's wikomnia kept him up all night reading wikipedia articles about why the banana is an endangered species of fruit.
