FrauFeli

And this one..the first line says "I love you", but written how you would pronounce it in really bad english, with a heavy german accent.

The second line says "princess", how somebody (well, the writer) could address his girlfriend e.g.

And, well, Keulchen is actually the petname itself, and a quite unusual one as it means the diminuitive of haunch or joint..hmmm.
(In german, there is no distinction between club and joint, but I can't believe that someone might adress his love as a club. :D)

Hu. That was a long explanation.
