This event occurs when you are stuck in traffic as a result of an accident on the three-mile bridge while emergency crews tend to the dead, dying or injured. All cars are at a complete stop and people get bored inside their vehicles so they step outside for some fresh bay air, talk amongst themselves about the poor suckers involved in the crash ,and generally get to know each other. It is a bonus if you happen to be near somone who has beer.
Bystander 1: "Hey man, you got a light?" ... "Crazy wreck, huh?"
Bystander 2: "Yeah man, ...looks like three or four cars up there piled on top of each other"
Bystander 1: "Man, I already told my old lady last week I was late because of a wreck on the bridge!" "She ain't NEVER gonna believe me now!"
Bystander 2: "Aw hell, man don't sweat it, here..have a beer"
Bystander 1: "Yeah, we'll just make this a bridge party"
