According to Wikipedia (my favorite source for quasi-truth and hamfisted misinformation) an Internet troll is: a person who sows discord on the Internet by starting arguments or upsetting people by posting inflammatory, extraneous, or off-topic messages in an online community with the deliberate intent of provoking readers into an emotional response or otherwise disrupting normal on-topic discussion.
I suppose that’s as good a definition as any. But did you know you can be trolled in real life too? It’s true. Let me tell you about it.
By the way, why do we say “in real life” when we talk about things that happen away from the computer? Am I not participating in real life when I do things online? Am I in some kind of suspended life or pseudo life? I don’t like that term, but it’s better than meat world.
