A word for human invented by the aliens in red vs. blue that means an animal like a skunk (or other smelly animal) that defecates, once it defecates the excrement turns around and defecates.

For easier definition please see Red vs. Blue episode 54 entitled "Hello My Name Is Andrew" on Red Vs. Blue .com. This episode is under season 3.

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.
