Thanks to someone around the Forum, I discovered the Non Sequitur comic strip. Different characters use expressions like "Politics-shmolitics" or "Ethics-shmethics" with a derisive/humorous demeanor (usually accompnying it with a wave of the hand, as if to get rid of the first term of the couple). And after that, they usually say or do something which is the complete opposite of the term.
My question is: would such terms ("shmolitics", "shmethics") be understood if mentioned in everyday life, or are they just typical of, and confined to, this comic strip in particular?
