what's trolling?

Hey, I know this is a stupid question, but what's Trolling? I'm so terrified that I might do it by accident that I want to make sure I understand what it is so I can avoid it.
Thank you!

Here you go mate, this should answer all your questions!

In Internet terminology, a troll is a person who posts rude or offensive messages on the Internet, such as in online discussion forums, to disrupt discussion or to upset its participants (see Anonymous Internet posting). "Troll" can also mean the message itself or be a verb meaning to post such messages. "Trolling" is also commonly used to describe the activity. For more discussion on definitions, see below.

I can understand.

Trolling is (as i understand it) is going around from post to post, not contributing anything, just making little comments and irritating people.

How do i know this?

I was scared that Trolling was reading a post and posting a comment. Sometimes I don't have anything to contribute that's intelligent so I got scared that I shouldn't be reading them either.
Thank you both for clearing that up, appreciated.

If you spot any other terms you are not familiar with it may be listed on A glossary of terms used on ATS.

The nastiest kind of trolls are those skilled at flamebaiting. The only thing you can do is to not feed the trolls by not taking the bait.

This can be especially hard sometimes, especially if you're like me and refuse to put anyone on ignore (because it can be fun to catch those trolls making a totaly idiotic statement).
