It's a fantasy role-playing game.

DM: You are Scanlan Shorthalt, a gnome bard . You are the member of the famous group of adventurers. Previously,   The party then, in trying to locate Grog's position, found their way, delving past the lava-fall of the obsidian rock duergar-Underdark, deeper in, discovering this cursed pit of undeath, bone shards, and glass. Upon traversing it they encountered one of these abominations that  they've  seen traces of left before—this weird, partial-elven, partial-tentacle monstrosity that slashed through the party, nearly killed Trinket, but was defeated by  Vox Machina .
  They  managed to make  their  way across this bone field and discover what appears to be a camp across a number of pillars in the distance.
DM: Yeah, very bad news. Okay. That brings us to Pike, who's also going to try and make her saving throw. Fails it, unfortunately. Pike dropped her shield, dropped her mace, and is clutching the side of her head, screaming silently as the pain is wracking her brain from the inside. That brings us to this duergar, who's going to rush over to the one who just banished his queen and attempt to-- his physical form begins to swell with strength and frustration. The duergar swings at you with his war pick. That is...
Player: "(singing) Oh, don't hit me!" I cast a little count, cutting-- what is it?
DM: Cutting Words?
Player: Cutting Words.
DM: Okay. So it's a 16. Go ahead and roll your d10 number. It's a d10 now.
Player: That's d10?
DM: It's a d10 now. You leveled up, yeah!
Player: I don't even-- I've never rolled a d10 before!
DM: Now you have!
Player: This is a d10?
DM: Yep, so it's a 16.
Player: It was a four.
DM: It was a four, so it takes that down from a 16 to a 12, which does miss.
Player: He misses! (all laugh)
DM: So as he rushes towards you--
Player: (singing) No, don't hit me!
DM: He stops for a second, confused. He puts the war pick down for a second like, "Wait-- argh! (groans) You gnome!" Doesn't know why he listened to you and is equally frustrated with himself now as he is you.
