Shit-chan

Chan is a term used in Japanese to refer to relatives or close people. But we don't listen to the rules outside of Japan, so Shit-chan is used for shittocks. Close to shitko.

That little shit-chan destroyed my book and laughed at me and told me not to tell anyone, or else she would tell my parents that I got mad and destroyed the book!
Someone was a shit-chan to me, and now I hate all of humanity!
