to troll

Behaving like a troll on the Internet.

the punishment of sitting below the table after missing every shot in a game of beruit (beer pong) for the duration of the next game.

One who posts a deliberately provocative message to a newsgroup or message board with the intention of causing maximum disruption and argument

Trolling – (verb), as it relates to internet, is the deliberate act, (by a Troll – noun or adjective), of making random unsolicited and/or controversial comments on various internet forums with the intent to provoke an emotional knee jerk reaction from unsuspecting readers to engage in a fight or argument
Trolling on-line forums as described above is actually analogous to the fishing technique of “trolling”, where colorful baits and lures are pulled behind a slow moving boat, often with multiple fishing lines, covering a large bodies of water, such as a large lake or the ocean. The trolling lures attract unsuspecting fish, intriguing them with the way they move through the water, thus enticing these foolish fish to “take the bait”. Not unlike unsuspecting internet victims, once hooked, the fish are reeled in for the catch before they realize they have been duped by the Troll/Fisherman

A commonly accepted definition for this is someone who does morally questionable things for the main sake of causing chaos or destruction. There are good trolls and bad ones. A good troll has properly calculated actions to cause as much disruption as possible. A bad troll is one who either takes it too far or simply relies solely on stereotypes, edginess, and slurs as trolling. What makes a troll even better is if there are layers to them - as in, not always insistent on being an asshole, and maintains the ability of being serious and nice, even. Not all good trolls have to fit this criteria, though.

When you post stuff online solely to get reactions.

Before the Internet, there were the mythical Trolls of old who ate farmer’s goats.

After that, there were and are the semi-human versions of trolls that still exist today in all regions throughout the world.

Trolls can be divided into groups depending on where they live, such as Beach Trolls, Hill Trolls, City Trolls, Suburban Trolls, Valley Trolls and a couple other categories which take on unique characteristics depending on their surroundings.

All trolls are socially predatory creatures and when young are usually obsessed with their exterior appearances, while neglecting development of their blackening souls.

Their interior ugliness comes out as they age, and they, usually, let their outer appearances go to hell, so that they are easily recognizable. But, the young and middle-aged trolls will sometimes fool you with their charm.

All trolls are shysters and tight-fisted money grubbers who will screw you on any deal while making it out like you are the one coming out ahead. They will usually always greet you with a smile and a handshake. Sometimes, they will call you “brother” or “lady” to throw you off track.

All trolls are shit stirrers, lechers & trouble-makers. They would be the first to try and get your “significant other” in the sack, screw you out of some money or slander you.
