It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, The Broker, a red-skinned, horned tiefling ambushes the party with the help of a sickly older lady and a scarred, masked humanoid. The Broker names  Nefertiri, Nethspira and Bellenore , sisters of Lillith, as his quest givers, and hints that he is acting legally.
DM: All right, Trinket (galloping sounds) rolls forward and (bear rolling sounds). Both of them try to move out of the way, they both get their dex save. All right, so Broker manages to pull out of the way just in time. However, the other, the big, thicker character doesn't quite have the dexterity to shift out of the way and takes the full impact. Okay. He suffers 14 points of bludgeoning damage as Trinket tears through.
Player: Eat it! Go, Trinket!
DM: He is knocked prone.
Player: Good job, buddy! Little buddy!
DM: That's Trinket's attack.
Player: Then I get a move, still. I mean, I get an action. I'm going attack him! I'm going to attack the Broker!
DM: For how that works for you and your bear, because that's his attack this turn.
Player: I mean, yes. I'm assuming that's his attack, or was that his move?
DM: Well, that's his attack. It's been a while since you attacked with Trinket.
Player: I get to have Trinket attack, and then I get to attack.
DM: Once, right.
