It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, Grog, left wide open from his reckless attack, is struck by all seven crossbow bolts. Trinket backs up, gets a running start, then curls up and rolls towards Count Tylieri, who dodges out of the way and claws into the bear as it passes.
DM: Okay. I'll let you do that because this is your full round to do that. Usually you would choose to cannonball--
Player: Or I do my two attacks?
DM: But because you aren't part of this combat fray and you're giving all of your round to him, I'll let you do it, sure.
Player: Okay. Thank you.
DM: Trinket comes out of the roll, turns around (roars) and strikes with the claw, swiping--
Player: He's trying to bite his neck like a vampire!
DM: Oh, bite him? Okay.
Player: Oh, shit. Ooh! That's good. 27.
DM: That hits.
