What's with the Wink?

Winks are meant to convey a message, symbol or suggestion. That message can be anything from "I'm an incorrigible sleaze" to "I didn't really mean it when I said I was sorry your dog got eaten by the neighbors." Generally, it's a good thing to be on the receiving end of a wink. Someone is trying to include you in some private communication so I usually just hope for the best and go with it. But what was a possible non-scummy reason this dad was winking at moms at the playground?
Back in the day, I met a girl a grade ahead of me who seemed to think I was great. She went out of her way to include me in conversations. And she winked at me a lot! I was only 15 and didn't want her to think I was naive so I just gave her a smug, knowing nod whenever she winked. After I had known her for a few months, I felt secure enough in our apparent intimate friendship to ask, "why do you wink so much?" She looked embarrassed and there was an awkward pause. "...well, I have this medical condition..." I was mortified and realized that all this time that I had thought she was drawing me into her inner circle and she had really just been having uncontrollable facial spasms. That was the last conversation I remember having with her as I was too embarrassed to talk to her afterwards.
The wink is a simple gesture, but it instantly adds an element of intrigue to any mundane interaction. As I was getting up off my bench to leave the playground today, I looked down and found some insight into this particular wink I had received from the married man. Apparently this one meant, "you're a nice enough looking lady, why don't you zip your pants up so we can focus on your lovely face instead of gawk at your underwear." I caught him watching with amusement as I zipped my fly and hurriedly dragged my toddler to the car.
