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,  They then encountered a very elderly goliath that you hadn't seen in quite some time named Shale, who spoke of the scouting crew that had been obliterated by the dragon. They followed Shale as she led them up the mountain, to where the dragon's current lair resides.
DM: What's interesting is, as you take the jug from him, it's empty but you still hear sloshing, even though it's empty as you hold it before you. You put water into it. It swishes around.
Player: Can I tip it upside down?
DM: Yep, you tip it upside down, and the water spills out.
Player: Anything else?
DM: Nope.
Player: Can I shake it? Any more swishing?
DM: You shake it, you still hear the swishing, yeah.
Player: Can I put my head in the jug?
DM: You do. (muffled) It blocks it, quite a bit. Your voice is ringing in your ears.
Player: Can I shake the jug?
DM: You still hear, around you (sloshing).
