look up any word, like kappa:
Chief Make Sure Nothing Is Shit Officer. The title reddit bestowed upon Steve Jobs upon news that he would be resigning from his position as CEO at Apple.
As the CMSNISO of Apple, Steve Jobs delayed production of the white iPhone 4 to ensure that it was free of any defects.

If Dell had a CMSNISO, all of their products would be discontinued.
