When a passing motorist yells insults at a pedestrian as he drives past him.
Some jock just pulled a drive-by shouting at the punks on the corner.
When you roll down the window of a car and shout something at a person or people. Usually an insult.
I saw a group of punk-ass teenagers walking down the street and there was a guy making out with his girlfriend or some bullshit like that, and I rolled down the car window and did a drive-by shouting of "stop infecting this town!!"
The instant in which a person passing you on the road yells insults or profanities for the duration of time you can hear them.
