from red versus blue contrary to popular belief a shisno is not only a "poop's poop" but can also be called at someone meaning anything.

MOM:here you go son your favourite cookies!"

KID: thanks mom, your such a shisno!"

OR
KID 1:wow kid your such a shisno!"

KID 2:what the hell is a shisno?"

you may NEVER tell a person what a shisno is, they have to find themselves without help.
