look up any word, like the eiffel tower:
The sum of unpleasant physiological effects following heavy play of Magic the Gathering; can start with but not limited to symptoms of fatigue, belly aches (from large amounts of geek food, paper-cuts, and in small cases waking up in a bed filled with Poison Counters or otherwise useless token/land cards
With a big game like that to end the night you will be sure to have a MTG Hangover.
