When you fart in a car with closed windows and the smell is so vile that the windows fog up and an undefined ectoplasmic substance accumulates on all surfaces.
Fat Abbott was Fartboxing his vehicle with such incredibly rancid bombs that he projectile vomited all over his ugly ass soccer mom SUV. His passengers weren't so lucky and all perished.

When a group of people get together in a car, close all the windows, turn on the heat, and then all release rotten foul farts. The first one to open up a door or puke loses. It also helps if you all go out and eat food that gets your bowels rumbling before you partake in fartboxing.
