A large rush of euphoria combined with disorientation, immense feeling of well-being (and possibly falling on your ass), caused by the ingestion of large amounts of marijuana. Often caused by hot-kniving or four foot bongs.
Dude, I had the awesomest potgasm last night, fell on my ass, then had the most satisfying poogasm.
