It's a fantasy role-playing game.

DM: You are Percival de Rolo, a human gunslinger . You are the member of the famous group of adventurers. Previously, In the Feywild, Scanlan lays forth Vax’s empty armor for Vex to see. Keyleth says she may be able to bring him back, but the spell would consume 25,000 gold pieces’ worth of diamonds -- which they do not have.
DM: As this is happening, you watch as he's looking at it and this hand goes up and starts clawing into his own eye socket.
Player: I'm going to use every dex I have. I'm going to slap fucking hard.
DM: Dex isn't going to help you so much as it's going to be a strength thing. Go ahead and make an athletics check. For you, for this, this would be an acrobatics to try and dodge out of the way.
Player: Strength check?
DM: Athletics.
Player: Oh, athletics, that's better.
DM: You're trying to slap it out of his grasp.
