Trolling / Troll

Troll or Trolling is a slang term used to describe any internet user or their behavior that is meant to intentionally anger or frustrate someone else, though not to be confused with cyberbullying, a form of online harassment carried out against an individual in a deliberately hostile manner (often without any reason) or pranking, which similarly involves playing jokes on strangers for one's amusement (but typically implies more coordination and intent).
