Game Jargon Definition: "Phys. Rep."
Phys. Rep. (noun) – phys·rep /fiz rep/
Phys. rep. is short for physical representation (but everyone calls it “phys. rep.”). This refers to physical objects that players can hold, manipulate, and interact with that are intended to represent in-game objects that a player’s character interacts with and uses. These real-world physical objects often have some resemblance—either in physical appearance or concept—to what they are supposed to represent in game. For example, a magical light spell may be represented by a glow stick, a gem may be represented by a colorful piece of plastic, or a sword may be represented by a foam weapon (or boffer).
