verb, intransitive
1.        To fish by trailing a line, as from a moving boat.
2.        a. To wander about; ramble. b. Slang. To patrol an area in search for someone or something.
3.        Music. To sing heartily or gaily.
4.        To roll or spin around.

Now, the Internet use of the word is usually drawn from meaning #1 (and is perhaps also related to meaning #2.b). With Mudcatters, I'd hope that we'd all fit troll in the sense of meaning #3 as well, at least every now and then. And some of the odder members of our community (including Guests) may even troll in the sense of meaning #4. ;-).

Now, speaking from personal experience, I find that Meanings #3 and #4 work well together simultaneously.

Go on! Try it! It's Fun!!!
