emissions testing

When you take a hose, attach it to a car's exhaust, put the hose into your anus, then place a heavy object (cinderblock) onto the gas pedal and prepare to die.

the process of sticking your bare ass in front of one's face, then blowing hard ass into their mouth; if they throw up immediately then it was an excellent fart, if they don't then they get to pinch a loaf into your mouth

Practical joke of choice for pranksters who are frequently spied upon. The prankster creates an elaborate distraction for the voyeur, while he has an accomplice (usually a butler) sneak behind the victim's car and lodge canned cookie dough into the tailpipe.

This will cause the emissions to back up and damage the vehicle, rendering in inoperable, ideally in an isolated location such as nearby an empty field. Other effects of the prank can be considered a bonus, such as if the cumulative pressure of the exhaust expels the dough like a cannon. The best case scenario is when the dough has been expelled and is discovered to have baked to perfection. The prankster and the victim may then enjoy the product together, assuming the two are on sufficiently amicable terms.
