A person from the lower peninsula of Michigan. The Mackinac Bridge separates the upper peninsula from the lower peninsula, hence "trolls" live under the bridge.

Plain troll:
"How dumb do you have to be to like this? My god, get off the internet"

"THIS SHIT SUCKS Y DO PPL LIKE THIS SHIT OMG WTF LOLOL"

Smartass troll:
"So she stopped singing in the middle of her concert to sign a painting? But how inconsiderate of her! That shows she has no affection for her audience. How did you know they wanted that painting signed? She ruined it, she bastardized the beauty of something someone worked so hard on. It clearly shows how everyone's maturity towers above hers."

Cannibalistic Ogre from mainly Scandinavian Folklore. Hairy, longnosed, brutish and Bug-eyed, they may also have multiple heads or horns. They come in all sizes, and either burst or turn to stone when sunlight hits them. They lurk in gloomy forests and dark caverns, and especially like to devour small children. However, they are usually pretty thick and can be outwitted with clever tricks.
The Females of the species are generally kinder and more intelligent, but still fairly hideous.

Gretir fought one.
Moomins are nice versions.
Gonks are sometimes called Trolls
Billy Goats Gruff are well known Troll Slayers.

Not cyberbullying.

Some people do horrible things that can make others depressed or even commit suicide. They call themselves trolls, and the media believes them, but they aren't trolls. They are cyberbullies and horrible people. Good trolls can make both people laugh in the end.
Person 1: I just sent someone death threats because they said something I disagree with! Trolling is so great.
Person 2: You aren't a troll. You're just an asshole.

Hunting for trolls.

Trollers hang around under bridges with troll guns at night (since trolls turn to stone in daylight), in the hope of bagging a troll head as a trophy.

As a VERY endangered (i.e. nonexistent) species, trolls are protected by law, and trolling is therefore illegal.
The police arrested two hobbits yesterday on charges of trolling.

Trolling is the term derived from the word "troll," which indicates trailing a fish along a baited line. In modern culture, trolling refers to hitting on guys when you are out, by baiting them with a little information about yourself or a flirty comment, and then playing hard to get. By planting the "bait," a girl will subsequently "troll" and find herself surrounded by a whole crowd of boys.

The act of trolling is an art-form, generally reserved for hot chicks out at a bar and/or club. However, it is possible to troll in all locations, such as the library or a coffee-shop, though that is a skill reserved for only the most talented individuals.

Note: Not to be confused with the noun "troll" (an ugly chick) or spamming message board (whoever does that cannot certainly cannot actually go trolling).
Girl1: I gotta get my make-up and tight dress on so I can troll tonight.
Girl2: Gen, I know, there will be a lot of trolling potential, like last night. I saw you surrounded by all those hot dudes.
Girl1: Troll or die, Liz. You gotta rage to troll.

Girl1: They see me trolling...
Girl2: They hating...
Girl1: But actually. Hatahs gonna hate when you troll so hard.
