When someone passes a super-cashed bowl (generally a water-pipe, but occasionally a regular pipe) which has long since been rendered unsmokeable. This usually happens because the "Geoff" involved doesn't want to have to load the next one. Origins: Central New Mexico.
"Dude, what the hell was that about? There was NOTHING in there?!"
"Oh, man, sorry. That was a Geoff Bowl."
