Posting a deliberately provocative message to a newsgroup, mailing list, message board, or other electronic community with the intention of garnering attention, gaining personal notoriety, goading others into angry responses, causing disruption, and/or inciting argument.
"But, Marti, it's so much fun to goad you people on."
"You know, the only reason I continue to post on this topic is because I
cannot express an opinion without being attacked in a vituperative and
hostile manner. It's sort of like poking a stick at a hornet nest."
"Telling me go F* myself will not stop the conversation. It only escalates it."
