Correction: "What does 'pansy attitude' mean?"
In addition to the answers already given, it can also be playful mocking of hesitation or nervousness. Imagine two climbers at the base of a rock. One is more experienced, one is less experienced.
climber1: "Wow! That rock looks bigger from this angle! Are you sure I can do this?"
climber2: "Forget that pansy attitude -- you'll do fine! Let's go!"
I hope this helps :)
