When the new player tries to meta game but can't find the info on what they just encountered
At the last session the player in question tried to look up the town they just got to because they recognized the name, they quickly found out that all I had was the name the rest of it all was made up by me on the spot.
But it's usually stuff like "what does flatfooted do" or "can I attack the enemy I attacked last turn if I'm blind" because I have no idea what's going on
