Finally, my strong suit!
TROLL - In an online community, a troll is a person who deliberately says or does something provocative in order to elicit an emotional response. The bigger the reaction of their victims, the more of a kick they get out of it. Trolls live off drama, thus "feeding the troll" is falling for their bait (whatever controversial thing they might have done) and making a big deal out of it. So a way to troll a Justin Bieber fan girl would be to post a shooped dead pic of him on a JB forum. Naturally, all hell would break loose, and the troll would be laughing like hell. IRL these people tend to be the ones that like to cause disruptions, make fun of others, and generally blow crap up.
You were right Flip, there are two categories of trolls, "lulz" trolls and "mean" trolls...
- Lulz trolls: Generally harmless, they only like to cause emotional reactions "for the lulz" (for laughs). Basically they just irritate a person so much with immature pranks that they completely lose it and start cussing them out online. People that get trolled by these trolls end up very humiliated but they either laugh it off or forget about it eventually. Example ***Mild cussing***
- Mean trolls: These types of trolls are a lot more cruel in their humor, and the pranks they play are much more complex and dangerous. They go far beyond what a lulz troll would do enough to make their victim actually emotionally wrecked (at the very least they might burst into tears). For example, this type of troll might spam up a site dedicated to the memory of a dead person with comments such as "he/she deserved to die for being _____". These sick people like to congregate in places like 4chan and ED and are easily provoked. Unlike a lulz troll which would usually just work alone, mean trolls attack in drones and remain totally anonymous. An excellent example of a victim of such trolls is Jessi Slaughter (google it, I'm not gonna link from here)
