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, Three fire towards Trinket and the other seven aim for you. One bolt bounces off the bear's armor, but the other two hit flesh.
DM: The other seven against you, Grog. Natural 20. Natural one. That's not going to hit, that's a natural five. 18?
Player: Misses.
DM: Natural one. That's a 19, that hits. A 19 naturally, so it's 27. One more. That's 18 to hit.
Player: Misses.
DM: Oh, these all have advantage on you because you did a reckless attack.
Player: That's right, I did.
DM: So the one that would have missed is a natural 20.
Player: Nay!
DM: That does hit. Natural 20 again.
