To take over the content of a message thread by changing the subject of discourse to a topic outside the purview of the original subject and/orforum, while maintaining the subject line. A form of amusement for trolls. Threadjacking is distinguished from flaming, as flames are a quasi-personal attack on a poster or on a poster's style of discourse, where threadjacking is deliberatly steering the discussion offtopic.
