Trolling itself may be understood as any of the following:
- To “make a deliberately offensive or provocative online post with the aim of upsetting someone or eliciting an angry response from them” (Oxford Living Dictionary).
- “The art of deliberately, cleverly, and secretly pissing people off, usually via the internet, using dialogue… The most essential part of trolling is convincing your victim that either a) truly believe in what you are saying, no matter how outrageous, or b) give your victim malicious instructions, under the guise of help.” (Urban Dictionary).
- To sow “discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the intent of provoking readers into an emotional response, or of otherwise disrupting normal, on-topic discussion, often for the troll’s amusement” (Wikipedia).
