It's a fantasy role-playing game.

DM: You are Grog Strongjaw, a goliath barbarian . You are the member of the famous group of adventurers. Previously, Scanlan jumps off of you's shoulder, pulls out his Wand of Magic Missiles, and fires eight darts at the giant, causing some of its flesh to fall off and expose bone. The giant turns its head to face him, aware that it is now flanked.
DM: Hits. He's very slow-moving and a very large target, he's very easy to hit, thankfully. So as you rush up, first, what you got?
Player: 22 for the first one.
DM: 22, nice.
Player: 13 for the second one.
DM: Nice.
Player: 15 for the third one.
DM: Nice! (whack) You slam the hammer into the side of one of its calves. It buckles for a second and you can see the muscle itself kind of snap and a piece of bone is now jutting out of the side of its leg.
Player: (singing) Now we got Grog's blood.
DM: With that, you swing the hammer around and slam it into the bone, actually jamming it deeper into its leg. (all yell)
Player: Yes, yes!
DM: As you pull back, these slow flames kind of burning the outside, you can see the flesh sizzling with the impact of the burning hammer. Swing it once in your hand, whack! Onto the other side, this time the actual leg bursts out that side and it falls almost a little bit, it's sort of walking on this stump of a leg now, you pretty much destroyed the bottom half of its middle of its calf to its foot, it's just slumping over, the toe's still kind of wiggling on its own. It's now half on part of its leg as at this point it kind of rotates in place towards you now, using one hand to get around as it brings this club up. Looking up into its face now, as you haven't really had a close-up on this, it's strange to see, you see there are similar features, you've encountered stone giants this up close and this personal, there is where your brethren, your blood comes from. However, half of its face is torn off by some sort of large claw mark. Where there would be an eye is just this sunken socket and there are these streaks of dried blood that long before the rainstorm came are just smeared across the face, and part of its jaw is broken open and you can see jagged broken teeth underneath, its tongue lolls out the side and it just (undead groan) reaches up with its club to come on down.  All right, so the first, it's going to come down and strike you with this giant club-like piece of heavy wood and metal. That's a natural 20.
