Ish wasn't being serious with the dude. She was just curious, wanted to fight a bit to amuse herself since it's in her personality to toy with her enemies and kill whenever she feels like.
To be honest, i was not surprised, it was to be expected by the way she was drawn. Fortunatly there was his "convenient" shaving problem. Not that I complain. :ROFLMAO:
I would probably call her that way if she participated in the annexion of my country. Ah yes, it's easy to follow the orders but if you're caught doing it, you will still get beheaded.
