Million billion or billion million?

Madame Mix-A-Lot said that she told her boyfriend that she loved him a million billion. And he said he loved her a billion million which is more. And she was mad that he won. But then Kelsie Jo said that there's no such thing as either of those numbers. Unless of course you were saying one million billions and one billion millions. And in that case, which one is really bigger? Madame Mix-A-Lot said we needed to ask a math major. We asked the desk clerks in The Pick and Dr. Badass Bierly said that they would be equivalent. You multiply them. So they love each other equally. :)
