Now that I know how to spell it, the mystery is solved

I never knew what the line "declining a Charlotte Russe, accepting a fig" in this song meant. Reading the description for the dessert I don't know why anyone would have a diet worth sticking that fast to (even if one doesn't care for coffee or Cognac). Still, though, isn't it just a trifle? It doesn't mention layering, but I've had non-layered trifles. I guess since it doesn't have fruit it's not a trifle, but soaked lady fingers and a pudding sound awfully triflish to me.

How would I have ever addressed this without the Internet? I would have puzzled over the song for another 10 years, at least.
