Simple, you just respond to the poster above you who attacks you and then you attack someone else.
example.
User 1: I attack with a rock.
User 2: Is hit by the rock and loses a tooth.
I attack with a barrel.
User 3: Dodges the barrel and kicks it down a hill.
I attack with a spoon
as you can see, the response to the attack is completely up to you, so feel free to get hit or dodge or whatever.
I attack with a spinning slap.
