The word secrets means “I don't care” when said using a tone that shows a lack of regard for the matter at large.
It’s usage originates from conversations between fog.hat and Faux Pause in which the later would enquire into the finer elements of the formers mixes, or musical montages, if you will. After fog.hat said he likes to "keep his secrets" in response to Faux Pause's requests for a tracklisting, the phrase "keep your secrets" became a common reply. As a result of heavy usage in the everyday language this phrase became shortened to just the word "secrets".
A: So what are you giving me for Christmas?
B: I'm not telling.
