Pasta keffasee-ay

The story:

I'd heard the song on the radio a bunch of times, and it was annoying me because I had no clue what it was saying. It sounded like pasta keffasee-ay, but since keffasee-ay is not even close to being a real word I knew I had to be wrong. At one point, I also thought they were talking about a pastor. I asked one or three friends, all of whom had no idea, until I thought to ask this one R&B lover I know. She told me the real words, but I still didn't get it until she explained to me that Courvoisier is a kind of wine.
