Cybershark

When reasonably new to an online game, people who regulary play the game act nice to you but try to cause dismay. This is mostly done through feeding false advice/ information to you which, ultimately, causes your game to crash, the admin banning you from the game/ server, and the likes.

A specific example would be a 'friendly' gamer telling you to type a random command into console which would cause your game to crash/ close.

Jill: You seem pretty angry!?

Mike: Some Cybershark made me lose my killstreak!
