It's a fantasy role-playing game.

DM: You are Caduceus Clay, a firbolg cleric . You are the member of the famous group of adventurers. Previously, The group eventually finds a place where they camp for the night. While they're there, Fjord convinces Jester to invite Avantika and Jamedi into Caleb's Tiny Hut.
DM: It is going to move, jump down from here, and begin to move this way to flank you, Caduceus. Now flanking you, is going to attempt to strike at you twice. Good to know, I forgot about that. Bite, this one's claws, so it's going to be with advantage. Okay, that is going to make it an 18 to hit.
Player: Why is it advantage?
DM: Because they're flanking you.
Player: Oh, goddamn it. Yeah, that hits.
DM: All right, so the bite attack. You take six points of piercing damage and the snakes snap at you. That is going to be a 19.
Player: That also hits.
DM: You take another-- ooh, that's ten points of piercing damage. At this point, as you're between the two of them, the one behind you that just put Jester to sleep, all its snakes snap around you, the back of your head and your neck and your shoulders, and you feel the poison through your veins. Roll another constitution saving throw, please.
