I was told by my ex and other women these exact quotes:

1) "Wow, you're confidence is sexy."

2) "You're such a jerk, but I love it."

3) "You don't need me, and that's attractive."

4) "You were different than other guys here, what's your name?"

Be different, be playfully jerkish (IT WILL NOT GET YOU REJECTED), and push boundaries. Let your intentions be known early.
