"secret" not in the sense that it's hidden, but that most people won't know about it. Because approximately nobody actually reads man pages in their entirety, they just get in to find out how a specific flag works and then get out.
Using "secret" in that sense instantly reminds me of hyped-up headlines for time-waster news stories. Most people don't know what 2^8 is, either.
