One way is to type a paper (they might know your handwriting) that says: "*Their name* is a (liar, some ugly name, etc.) Sign here and pass it on." However, bullying is never good. By getting such a revenge, you are being a bully, thus making you no better than the other person.
It might or might not work and you might or might not get into trouble. Once it goes around the whole school, you have yourself a pretty awful rumor and you could tape it to their locker. However, doing so is a bad idea.
Karma has a way of coming around. You may develop a conscience, you might help push another student to harm themselves, and you might even get caught. So don't do it.
Forget it. You will just get into trouble and since you ask this question I suspect you have all ready been in trouble. This is not good and revenge in never good.I suggest you "chill out" and start thinking about school rather than revenge since it is a waste of time and energy.
