It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, The one in front of Grog quickly moves to his side and grasps onto his armor, pulling him in. It attempts to bite into the goliath, but its fangs catch and deflect off of the little bit of chainmail around his neck, given to him by Scanlan.
DM: So this third one over here is going to attempt to come after you, Vax, closest to it. That is a 24 to hit.
Player: Well, that hits, but I'm going to use Uncanny Dodge.
DM: Okay, to reduce the damage?
Player: Yeah, by half.
DM: That's 2d4 slashing against you. Ten points of slashing damage.
Player: Is the half?
DM: Yes, it's going to try to claw you again. That's a 12.
Player: Nope.
DM: Yeah, so the first one slashes across the side of your shoulder, but you manage to pull out of the way just in time to lessen the impact. This, however, sets you up for the easily dodged second blow. You swoop out of the way just barely in time, feeling the wind (whoosh) above your head. That ends their turn. Now we're at the top of the initiative order: surprise round. This would not have been enough noise to wake you guys yet, so you're going to hold on until somebody can get your attention. Top of the round will be Vex.
