I stab you in the face.
The next user is stabbed in the face.
But my face is your face, so you stab yourself in the face while stabbing my face at the same time, but you didn't stab my face either, so you stabbed your face.

The next user is the one in the crossfire of all the stabbing.
I stab the crossfire's face.
The next user is the crossfire.
I stab you in the face first.
The next user is a face getting stabbed.
