An eruption of laughter. Can be brought about by a joke, an epic fail, personal shame, or just by something that's really funny.

The point where one believes that they may erupt/explode in LOL's. (An Abbreviation for Laughing out loud). Commonly affiliated with ROFL or LMAO. Only the most humerous of events should be appointed a LOLcano.
