Errors & Omissions 

When a douchey and self defined "very experienced" individual points out an apparent mistake with very little to no actual knowledge of the matter at hand.

Douche: "Have you had an opportunity to complete that task I've requested?"
Person: "As a matter of fact, I have not. It is actually physically impossible to complete that at this time."
Douche: "Hmm, I believe this is going to go on my 'errors & omissions' list."

pop n fresh emissions test

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.

shit dawg lets see how he likes a pop n fresh emissions test all up in his new ride!!!
