The vandal should have just gone with "bitch." Misspelling epithets takes the sting out of the insult -- the intended victim realizes you are a total looser. ;)

Well at least you know that whoever did it is a moron.

Hit the guy with a dictionary

I can't stand a dumb person. If you're going to call someone that, at least learn how to spell it.

You gotta have some admiration for the vandal who at least made the effort to deliver high-quality slander to you. Most people wouldn't take the time. It's good to see that craftsmanship is not totally dead.

Write on their locker: "It's douchebag!"

Become a grammar nazi and write it back on their locker *douche bag. That will show them.

Shut up you doosh... erm... dewsh... uhh.... dowsh? Doesh bag?
