The art of completely raping the enemy team with vehicles in games such as Halo and Unreal Tournament 2004. Often linked with roadkill.

Also an announcement in UT2004, which is played if you squash an enemy in the Manta. This is where the phrase originated from.

The satisfying act of jaywalking, but in a car, across a crosswalk full of people. However, this only counts if there are casualties, so its good to have a strategy. Since this is solely for fun and such a positive experience, feel free to make it more fun, like with a blindfold!!

When your a horrible parent because you gave your young child the key to the car, and he takes off driving it down the road, and then you realised you gave him the opportunity to Go Commit Vehicular Manslaughter and that your responsible for them
