The "trollface", first appearing in 2008 Created by DeviantArt, is occasionally used to indicate trolling in Internet culture. Modern usage of the word itself dates from 1980s. It usually means being mischievous or intentionally angering someone.
In Internet slang, a troll is someone who posts inflammatory,extraneous, or off-topic messages in an online community, such as a forum, chat room, or blog, with the primary intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion. The noun troll may refer to the provocative message itself, as in: "That was an excellent troll you posted."
While the word troll and its associated verb trolling are associated with Internet discourse, media attention in recent years has made such labels subjective, with trolling describing intentionally provocative actions and harassment outside of an online context. For example, mass media has used troll to describe "a person who defaces Internet tribute sites with the aim of causing grief to people".
