The idiom conveys a sense of secrecy, as if the person engaging in the action is operating outside the bounds of expected behavior.

The origin of the phrase "on the sly" can be traced back to the 17th century. It first appeared in a literary sense in Samuel Butler's satirical poem "Hudibras" published in 1664. The line "Some did the deed with vast direction | And Slily stole their Recreation" showcases an early use of the idiom.
