Is it just me or?....

Chock their wheels on the inside edge with a few half-bricks and watch them make a bell-end of themselves trying to reverse out of their parking spot. Oooo, undo an exhaust clamp as well and give it a good shake to make sure it'll blow when they start up, then everyone else will notice their reversing antics too lol.

Just punch them square in the face... that's how i stopped people f*cking with me, works too

True story, I also find this method to be effective
