troll jacked

adj often executed by the notrious /b/ community/4chan'ers alike (though definitely not limited to), it is when a group of people take over a online thread using fake/temporary user names/accounts and create inflamatory posts for the purposes of eliciting anger for their own amusement.

CNN had posted a controversial article but their comment thread was troll jacked by 4chan'ers with statements that made people angry and uncomfortable.
