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.

Buy the plush
Person who accesses internet forums with the expressed purposes of stirring up trouble or deliberately post contraversial material adverse to the general feeling of the majority of posters, or more often to be just plain fucking annoying and offensive. This is usually a result of an insane egotistical complexity that they cannot resolve in normal life, just plain old fashion attention seeking.
See Craig David on the Chavscum forum, and various other obvious and deliberate trolls.

The Urban Dictionary Mug

One side has the word, one side has the definition. Microwave and dishwasher safe. Lotsa space for your liquids.

Buy the mug
A person who, on a message forum of some type, attacks and flames other members of the forum for any of a number of reasons. A real troll usually flames threads without staying on topic, unlike a "Flamer" who flames a thread because he/she disagrees with the content of the thread.

Trolls are people who flame the posters themselves, they flame because of rank, previous disagreements, sex, status, ect.

Trolls MUST NOT be confused with Flamers, who attack threads based on thier content or lack thereof.
