U-lock Justice 

Using a 2-5 pound piece of steel, originally intended to lock a bike, to do cosmetic damage to a 2,000-10,000 pound piece of steel originally intended to transport human beings used to purposefully do physical, possibly lethal damage to a human being on a bicycle.

After being repeatedly honked at and passed very closely at high speeds I enacted U-Lock justice. The driver now might think twice before purposefully endangering the life of another human being.

U-lock Justice 

Vigilante justice taken against aggressive motorists or "cagers," by bikers.

The heavy U-lock used to lock the bike is used to do damage to a vehicle, like by taking off a mirror.

U-lock Justice is not legal justice, but it's the only justice some cyclists get for being hit by inconsiderate motorists.

I saw some stupid cager get a dose of U-lock Justice after he tried to hit that messenger.

U-lock Justice 

When pansy bicycle messengers vandalize automobiles with their bicycle lock. Usually because they think they are above the laws of the road yet still want to peddle in it so they sometimes have accidents with automobiles.

ME: "Some sissy on a bicycle just hit my car with a lock"
FRANK: "Why did he do that?"
ME: "Dont know, he was weaving in and out of traffic and I almost hit him."
FRANK:"Ahh, in their little bike world they call that U-Lock Justice."
ME: "Sounds like something a 13 year old made up. LOL"
FRANK: "LOL"

U-lock Justice 

The preferred method of vandalizing a car by a Bike Nazi or other irresponsible or self-righteous cyclist. Because few police agencies wield power over cyclists and they can quickly disappear, the vandal frequently gets away with his crime.

U-lock Justice is the Bike Nazi term for it. Vandalism is the most common term used by normal people, including drivers, auto passengers, pedestrians, police and insurance agencies.

U-lock Justice is often dished out to drivers that the Bike Nazi feels is deserving, though many times it is applied to drivers who simply do not notice a cyclist because they're not riding safely or legally.

Yesterday a Bike Nazi cut me off and I honked my horn. He turned around and whacked my car with a metal bicycle lock, denting my fender. The body shop repairman said I was a victim of U-lock Justice.
