Playing the game is selecting Rock.

Playing the meta is selecting Paper because you know most players choose Rock. Its a strategy completely outside the obvious rules of the game.
When your friends figure out thats what you’re doing and so they play Scissors, that forces a change in the meta so now you play Rock.
