Hacker is something no golfer ever wants to be called. Hacker is a derogatory term in golf that means: someone who rarely plays golf so is quite bad when they do; generally, any golfer who is just not very good at it; a mediocre or poor golfer who displays bad golf etiquette and/or poor sportsmanship.
The term was coined in 1994 by a Cult of the Dead Cow (cDc) member known as Omega in an e-mail to the group. Due to the variety of meanings of its root words, hacktivism is sometimes ambiguous and there exists significant disagreement over the kinds of activities and purposes it encompasses. Some definitions include acts of cyberterrorism while others simply reaffirm the use of technological hacking to affect social change.
