It's safe to say that this guy is going to get his ass kicked eventually. He decided to "prank" people that were taking up more than one parking spot by spray painting the parking lot lines across their car to illustrate where their car should have been. The paint, though, is fake spray paint and simply wipes off.
Some people are really protective of their cars. If this guy gets caught, even if they know it's fake, he's still going to get a beat down. On the other hand, everyone hates it when someone takes up more than one spot. So we're pretty torn on this.
