"wine and dine" means to ply someone with liquor and food, figuratively. You can wine and dine prospective clients, your future in-laws, or your date, hoping to impress them favorably or win them over. The "69," I suspect, refers to a sexual position (one which involves fellatio and cunnilingus simultaneously, in the case of heterosexual relations).
Yes, Bibliolept.That's what I was thinking, thank you.
Turokcalde! I've heard this expression many times, first in my life in an Alanais Morisette song (He took me out a wine, dine, 69...,but didn't hear a damn word I said.)
