look up any word, like sex:

pcv
Abbreviation for Penis Compensation Vehicle - A vehicle altered to make a cowardly driver feel bigger than he really is, usually with lift kits, bull testicles, winches, and various off road accessories that will likely never be used as intended. Most common PCVs include but are not limited to pickup trucks and sport utility vehicles.
I got cut off by some teenager in a PCV, but he ran inside crying to his parents when I tried to confront him.

P.C.V. = "Probable Cause Vehicle"

This is a vehicle that is just begging to be pulled over by the police either because of the car, itself, the passengers, or the behavior of the car and/or passengers. Often has a lot to do with the location of the car at the time. This, itself, will give the cops all they need to legally wrangle even an undeserved pull-over and search into a lawful bust of the occupants.

Any number of things can cause a car to be a P.C.V. - most have to do with the environment in which the particular car is found. A P.C.V. might not be a P.C.V. in one place, but becomes one in another. In other words, wrong vehicle in the wrong place.

It is possible for a P.C.V. to be a P.C.V. everywhere, though.

If you find yourself in a PCV, don't bitch at the police for pulling you over. They're doing their job and you were probably being a moron. Automobile profiling is an effective law enforcement tool.
That beat up panel van with Florida tags full of Latinos doing exactly a double nickel on the New Jersey Turnpike is the classic P.C.V. (high probability of running drugs to NYC).

Your AMC Pacer with the bondo quarter-panels and the primer paint-job was fine in Newark (NJ), but it became a P.C.V. as soon as you entered Bergen County.

P.C.V. Alert! Homey with the humps in the trunk cruising the burbs is going to get treated like Rodney King.

Poor Trevor...didn't realize that driving his daddy's Beamer to 118th Street to score some blow put him in the hot-seat of a P.C.V. Now he's AFU and SOL.

Cheech and Chong's hippie-filled van with the expired tags leaving a trail of purple haze behind it would be a P.C.V. no matter where it is.

PCV stands for positive crankcase ventilation and it is a vacuum controlled valve on or near the valve cover of an engine that removes blow by gasses from the crankcase and allows them to be reburned
That oil leak could be caused by a defective PCV valve.
