The title of this cache is good advice.
In internet terms, a "troll" is one who causes adversity for seemingly no better reason that to start trouble. Often, trolls will be completely unwilling to listen to reasonable arguments, and really just want to keep trouble going as long as possbile.
Often, trolls don't see themselves as trolls. They're just passionate people about a given topic and want you to not only see their point of view, but adopt it as well.
One example of "trolling" is similar to the following:
"Christian Slater is the worst actor of all time and anyone who casts him in a show is a moron"
While that statement happens to be true, it's also an example of trolling ;-)
I myself have been a troll on occasion, as has pretty much anyone who has been on the internet ever. Whether or not you realized it either now or at the time, is another matter.
The cache title is the recommended course of action whenever you encounter a troll. The best advice is, just shut up and let it die. The worst thing you can do in the world is watch watch a Christian Slater TV series, but the worst thing you can do to a troll is to give them validation by actually replying and acknowledging the fact that their point of view is worth stating publicly. That's what they're waiting for. And trust me, well thought out, rational facts mean nothing to trolls. So seriously, just walk away.
Oh, the cache is under a bridge, and trolls live under bridges. Mythical trolls, not Christian Slater fans. At least I'm not sure about them...
Disclaimer: I'm sure there are many people out there who Christian Slater is a fine actor and Broken Arrow is a cinematic classic. Bless your hearts. I don't really care either way. Just needed an example to make the cache page funny.
