The act of causing or contributing to a motor-vehicle accident on the road and fleeing the scene so as not to be identified and held responsible. Luckily, a more concentrated police presence near busy intersections has meant that there's only been one bam and scram over the past two years. No, officer, he left the scene—it was a bam and scram!

slang To leave or depart very quickly; to hustle away. Often used as an imperative. I think I hear the police coming. Let's scram! Scram, you filthy raccoon! Get out of here!
