An extreme form of the stoner, the megastoner is an individual whose near-constant marijuana use reduces him to a pathetic state of drooling semi-retardation. The megastoner is unable even to play video games or engage in normal conversation.
Did you see that megastoner? He smokes every five minutes. He can't even wipe his own ass.
