Messing around with another person's vehicle (ie: wrapping victims car in caution tape, filling one's car with trees and shrubbery, placing a skate ramp on top of a person's car, etc.) If no props are available one can sneak into someone's car and turn all the dials and switches so that when the owner starts the ignition, the entire car starts going crazy (ie: wipers at full speed, heat on full blast, radio on max volume, etc.) Also, car fagging can be performed on a moving vehicle (ie: passenger grabs the keys and turns the vehicle off while driving, passenger pulls emergency brake while on the highway, etc.)
Person 1: "Hey, why is your car wrapped in caution tape, was there a crime?"

Person 2: "No. That jackass down the street car fagged me."

Person 3: "Well, I guess we have to get him back. Time to go car fagging."

Get the Car fagging mug.
Someone who is obsessed with talking about car. You will struggle to change subject and even if you do, it will end up back at cars. Their banter consists solely of cars.They frequent car park(McDonald, Golfworld etc) in their shitty cars to talk about there loud farting cars. However not all people who like cars, are car fags. Basically if the person can talk about anything other then cars they are not a car fag even if they have some riced out shitter.
All the car fags, are talking car fag shit over in Mcdonalds

Not only do they only talk and take care of their cars, but they also customize it with rims, lights, make it sound loud, and change the suspension. Seeing one in real life is a terrible experience and you will usually see them parked in Walmart at night showing their whip off.
"Dude did you see that dude's car with the lights?"
"Yeah he must be a car fag."
