The term has aged poorly, comparable to the way MLG has. Trolling (because no one could have known this!) used to refer to intelligent toying with others to incite rage. However, creativity has waned and now the word is known by basically anyone with an internet connection. Monkey see, monkey do.
This has been a public service announcement.
