i had a jeep wrangler in high school that this fagot smeared a ****gin cheeseburger on my jeep (*which was new at the time). i was pretty pissed so to get back at him; now i warn this is graphic)!!! he had some piece of **** saab so i took a **** in a ziploc bag and then stuffed it up into his starter/exhaust manifold and im sure after liek 5 minutes his car smelled like burning turds and he couldnt figure out why. funny thing is i never got messed with again. another trick is the fix a flat thing, put liek 3 cans in a tire when it sits for a while and have the dude drive with a majorily imbalanced wheel
