Hmmm dude what was it that u were keying? Import cars? Domestic ? SUV's with large carbon footprints?maybe the cars with bumper stickers that say my horse tramples yor peat bog, or maybe " I own the road, if anythings on it I run it off or over"(actually I'd probably key that !)
my favorite alternative to keying cars is a bumper sticker some friends used to slap on giant trucks They said "you'd understand why i drive this if you looked in my shorts" or something like that. It was on a special bumper sticker that is really hard to take off....
my favorite, of which i will neither confirm nor deny, from some deviants i ....well....just maybe know, you know: is the following, the bumper stickers with the "i (heart symbol) my silouette of a dog, cat, etc., a sticker with a screw on it somehow gets placed over the heart symbol.
