Noob: Chances are, if you’re reading this, and thinking of starting to play games, then you are a noob. Derived from ‘newbie’, this word is used to describe people who are inexperienced at gaming in general, or at any specific game.
Pwn: Pronounced ‘P – own’ this word is used to describe a humiliating defeat. “Did you see Chris get pwned?”. It is believed that this word started as a typo, deriving from the word ‘own’; as the letter ‘p’ is next to the letter ‘o’ on most keyboards, a slip of the finger could have happened.

Griefer: Griefers are game players who seem to get their enjoyment for causing other players problems: that is, giving other players grief.
Co-op: Like the popular British supermarket chain, this is a shortening of the word co-operative; in gaming, it’s when you have to work with other players to achieve a common goal.
