Is the popped collar really considered sexy?

I was at work today and forgot to button the 2nd to the top of the collar. And my co worker asked if I was tying to be "sexy" I had no clue what she was talking about and asked her what she was talking about and she said that I had a popped collar and that guys apparently do that to be "sexy". That never occurred to me though... but is it really true or was she lying? (Picture of the shirt I wore today and how I wore it)
