1. The occurence when no other vehicles are around to see you run or roll through the stop sign.
2. Condition of a stop sign or light when one does not care what the other asshole motorists think when he or she has failed to stop.
passenger: You totally blew through that intersection without stopping. Aren't you worried you'll get caught?
1. Not completely stopping at a stop sign, but going through it. The majority of drivers do this.
2. In those rare instances when for some reason a stop light won't turn green, or turns red for no real reason. Usually when the light is old and doesn't have a sensor to tell it where traffic is coming from, but there can be other factors.
1. This sign isn't stoptional. There's a cop right over there.
2. Dude, there's a bus parked on the sensor over there. The light is never going to turn, just go through it. It's stoptional.
