Sorry it has to be said!

Gossip is idle talk or rumor, especially about the personal or private affairs of others.
While gossip does or maybe doesn't form one of the oldest and (still) the most common means of spreading and sharing facts and views, it also has a reputation for the introduction of errors and other variations into the information thus transmitted. The term also carries implications that the news so transmitted (usually) has a personal or trivial nature.
Some people commonly understand gossip as meaning the spreading of dust and misinformation, as (for example) through excited discussion of scandals.
How to Resist Gossiping
You hear a lot of.. "Oh My Goodness! Sally is so ugly. It looks like she jumped into a cat litter box!" talk in high school. It is hard not to gossip, we've all probably done so at one point or another. Let's face it, it seems impossible, but it is possible.

[edit] Steps
Start off by thinking about something else rather than what you want to gossip about.
Know that if you are in a group and they are picking a name and saying something negative about a person, try biting your tongue (literally), spacing out, or just don't pay attention to what they're saying. If you really want to make a statement, when they ask you why are you so quiet. Simply reply, "I'm trying not to talk about people behind their backs."

[edit] Tips
When you feel the urge to point out that the girl next to you that has a mustache, think of yourself in her position. Now that your the one with the excess facial hair you may not feel so inclined to gossip about it. You wouldn't like someone saying that about you now would you?
If you still feel yourself wanting to gossip about someone else, try to think about why your really doing so. Can you really not stand her or are you perhaps jealous? Either way it often helps to even just mentally give them a compliment instead of a mental diss. Think Positive!
When people see that you don't talk badly about other people, they often seem to grow closer to you because they can trust you to not talk about them behind their backs. You also gain a lot of friends this way.
Keep a rubber band around your wrist. Whenever you talk bad about someone, snap the rubber band. Its a painful method, but effective. .

I'm sure that we have all come across problems with gossiping. You definitely learn who you can trust and those that you can't. Every couple of years I come across someone that just likes to stir the pot when not necessary and try to hurt peoples feelings. I've learned to steer clear of this type of person. What really hurts is that I had been for warned and didn't listen. Sorry..
