Depends on the mood and whom I'm with.
What works best for me is saying stuff in Italian (I speak it fluent). Most women just melt when hearing it
The real dinger is if I'm actually into the women or not. If I actually care then I say nice things. Otherwise sometimes I'll say some crazy ass funny shit in Italian...and the women thinks I'm being all romantic, lol.
Being Bi-lingual has its perks, lol.
