Related to "magic phrases", what expressions or turns of phrase work for you, but don't work well for a typical real-world audience?

I tend to use "it's not magic" as shorthand for "it's not some inscrutable black-boxed phenomenon that defies analysis and reasoning". Moreover, I seem to have internalised this as a reaction whenever I hear someone describing something as if it were such a phenomenon. Using the phrase generally doesn't go down well, though.
