It's a fantasy role-playing game.

DM: You are Beauregard Lionett called Beau, a human monk . You are the member of the famous group of adventurers. Previously, With all the enemies handled, Molly douses the flames on the dead priest's head and calls Caleb out of his withdrawn state. The rest of the party searches the room for any valuables.
DM: As you're doing that, "Good job!", you look back just as two arrows go flying towards you from the two other gnolls. They both have disadvantage, I believe, right? Because you took your defensive stance.
Player: Yep.
DM: All right, which is good because that would've been a 20, and an 11.
Player: Miss, miss.
DM: Well, that's the first attack. I rolled a 20 and 11. You dodge out of the way. The second one is going to be a 21 and a 22. That hits.
Player: See if I can catch another arrow.
DM: You take six points of piercing damage.
Player: I'm going to do my Deflect Missile.
DM: Reaction, right.
Player: I'm going to try and do like a frisbee catch in the air.
DM: Okay. Go ahead and roll your die.
Player: It's a d10, right, d10? What was it, six damage?
DM: Six piercing damage.
Player: Five plus my seven, so yes.
DM: All right, so the first arrow you dodge out of the way, and the second one you see it coming out of the way. There's a brief moment where time seems to (whirring) and you catch it right in the middle of your hand. It pulls you back a little bit and looking down you can see the arrow is there, right in the middle of your grip.
