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, Being the adventurers they are, they took it upon themselves to leap out into the forest of the Vesper Timberland, found and hunted down this hydra, fought it, and upon slaying it discovered that there was another group also hunting this hydra. An actually sanctioned group, and hunting this hydra is considered illegal in Vasselheim unless you had actually been contracted to do so.
DM: Eight? Okay. It's hard to tell. It looks like this area is not heavily traversed, and what little sign of footprints there are scattered enough that it's hard to make out a specific print. But I mean, they have been traveled before.
Player: I'm looking over Thorbir's head and looking for traps as he walks from behind. 22.
DM: 22? All right. As you guys are walking forward and going through this, you get about 40 feet forward before you catch that there is a slight divot, a small drop in the dirt, and one looks like a section of intentionally placed plate of some kind.
Player: Wait a tick. I'm going to go up to the edge of it and try to inspect it and see if I can find a trigger or see how it works. Six. And that is, what is that, perception?
DM: Are you checking to see how it works?
Player: I want to see if I can disarm.
DM: To disarm it. Okay, that would be with your thieves' tools. So this would be a dexterity plus your thieves' tools, so plus seven.
Player: That's a 19.
DM: 19? Okay. As you go to the plate, you stop and look up at the walls to the side, and to each side of the wall you can see these tiny little holes, these little quarter-sized, gold-piece-sized tunnels bored multiple places on both sides of this wall. And you take the plate, you realize this is a pressure plate-based trap, and taking one dagger, you slightly lift it. The second one, you eventually find beneath where the trigger apparatus is, and you gingerly cut each part of these spring-loaded triggers until eventually the plate rises more and more and more and you remove the last bit, the plate tips over, and the trap itself is disarmed.
