Basically, if you're an idiot, they're the people on the internet that try to aggravate you. This mostly happens to Justin Bieber fans, horny girls and guys on omegle, and idiots in general. Either that, or the troll just has too much time on their hands and trolls any random person for shits and giggles.
Stranger: m/20/california surfer with ton of tattoos, willing to share pics.

Troll: Cool story bro.

The act of sitting under the beer pong table after failing to make a single shot during the previous game.

As an added bonus, the person sitting under the table may shout "FEE FI FO FUM" intermittently.

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.
Person #1 from upper peninsula......"Hey man, aren't we partying with your cousin from Detroit who is coming into town tonight?"

Person #2 from upper peninsula......"No, that fuckin troll won't be here until tomorrow."

Rhymes with 'stroll', it refers to a style of fishing where a baited line is drawn in front of fish hoping that one will bite. The person doing is a troller.

The analogy to a baited message hoping for bites is obvious.

Really, a troll is just an intelligent person. Independently trolls, flock to 4-chan where they converge for seasonal mating rituals, called "raids". Coincidentally, trolls are also considered funny amongst their own kind. Kindly, if trolled, back down, as not to aggravate the beast. Always listen to what a troll has to say, it is generally funny. Socially awkward nerds, who intelligently insult the more popular group on social media can be considered trolls. The troll is a vicious creature. Let trolls roam freely on your Facebook, as they will surely correct any idiocy upon it. Especially, when you are a teenager. You should probably know I really like Rick Astley, so go look at the first letter of every sentence.
This post could be considered an attempt at a troll.
