While in a moving vehicle, puking into a container and then tossing the container out the window, thus making a stop to puke on the side of the road unnecessary. It is especially used when the container strikes a mailbox or a pedestrian on the side of the road in passing.

This is also known as a "drive-by vom bom" because it is done in a moving vehicle.
Jo: "We need to stop the van now! I'm going to throw up!"
Bart: "We are going to be late. Just puke in the grocery bag and we'll toss it out the window."
Jo: "Okay, I'll throw the vom bom out the window the next time we pass a pedestrian."
