DLS

Short for "Dirty Little Secret"

Self-explanatory. A secret thing (such as a love affair, or shameful thought) that you don't want anybody to know. The phrase was popularized by the song "Dirty Little Secret" by the All-American Rejects.

Yeah, we see each other every week and my wife doesn't know. She's my DLS.
