It's a fantasy role-playing game.

DM: You are Pike Trickfoot, a gnome cleric . You are the member of the famous group of adventurers. Previously, This isn't going to hold for long! Let's get the hell out of here.
DM: Okay. So, you grab onto Tiberius, you rush over after healing him, grab and start dragging him towards the entrance. At half-speed you manage to get him three squares, that's as far as you got. As you're pulling back, the king, as a reaction, gets one strike on you with his sword. That's gonna be a 19.
Player: Get outta here.
DM: Your AC is 20?
Player: It's 20.
DM: So the blade hits you--
Player: I just flip him off.
DM: The blade comes down towards you, but with a flash of divine energy in your shoulder armor, it just gets deflected off the side and you glare at him out of the side of your face. And continue to drag Tiberius out of the room.
