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, A scuffle ensues as they chase down a necromancer, a number of cultists, and some creatures from the Shadowfell. During the fray, Scanlan gets Sprigg back on his feet, and Keyleth kill a couple of the cultists with a Firestorm.
DM: Well, we have dagger, dagger, dagger. Now we have attack, attack, attack, attack, attack, attack as our next t-shirt.
Player: I'm dumping a level two Smite into this, against an undead. That's seven, 10, 11. Ooh, it's cocked. 17 for that hit.
DM: 17 with the additional--?
Player: With attack-attack.
DM: Right. Well, but you said you dumped Divine Smite into that?
Player: Into that one.
DM: You did the additional damage for it being undead? Okay, so that was how much total?
