Why do you hate meta-gaming? (And what does it mean to you?)

[Psikerlord#]

I understand RPG metagaming to mean using knowledge the PC probably wouldn't have. Like golems might be specially affected by the slow spell or something. I don't really care about it, the PC might have heard some tale that reflected the info.

Frankly I'm glad the player is enthusiastic enough to have read the monster manual ! We might have a future DM on our hands!
