I thought that "wine dine 69 me" meant "have dinner and drinks with me, and then leave on highway 69". I just assumed "69 me" was an idiom that meant "love 'em and leave 'em" or meant he didn't call her the next day. This is a lyric from an Alanis Morissette song, but my belief extended beyond the song.
