I've wondered about this in the past, and the "pig trolling" thread made me think about it again.
Shouldn't it be "trawling" - as in what fishing boats do with their nets?
Didn't there used to be expressions like "trawling for babes" (i.e out with the guys on a night on the town). The "pig trolling" certainly seems to have a fishing analogy, and seems to be that it should have been called "pig trawling"
Similarly, the "trolls" on this site (and other internet sites) - what does it mean to be "trolling"?? I wonder if it originally was "trawling" (as in "trawling for trouble") and at some point, some dude was saying it to another out loud, and it acidentally got mis-typed as "trolling" (since the words sound identical). And it probably stuck, because we can all imagine a troll - being a mean a malicious creature out to cause trouble.
Any of you internet dorks actually know the origin of this word? I'm betting it was originally "trawling" and not "trolling"
So there.
Now that I've wasted your time, and procrastinated my own, I'm getting back to work
