"Proc" is a computer gamer term. It rhymes with "dock." "Proc" is both a noun and a verb.

"Proc" and "proccing" is used to describe whenever a random gaming item activates, or a random gaming event occurs. Particularly common for massively multiplayer online games, procs are random events where special armor or weapons provide the user with temporary extra powers, or whenever the opposing monster suddenly becomes more powerful in some way.

  • e.g. "Whenever my trinket procs, I get extra dodge for 20 seconds"
  • e.g. "My rifle speed-up never procs enough for my tastes."
  • e.g. "My ring usually procs once every two minutes"
  • e.g. "Don't let his lightning charge proc, or else we are all dead"​

Here are some examples of gaming procs:

  • a special spell cast suddenly becomes available to the player.
  • a sudden armor bonus will activate and last for 10 seconds.
  • the player will temporarily receive more health points, allowing her to fight a monster longer.
  • the monster will suddenly gain extra strength to crush the players in front of him.
