In the first part of your post, you type how what he person put in the second part of their post kills them. It must have something to do with their object. Then in the second part of your post type the name of an object. For example.
(Insert death of some sort here.)
Object: Raw fish.
You drop the fish, which lands right where you are stepping. You slip on it and fall right in front of a speeding vehicle.
Object: Dust pan.
Consider Human no. 2's post as the start-off.
