P. D. Swy?

Why P. D. Swy?
My husband likes to switch syllables of words around and rhyme. Made things interesting when the kids were really little, lots of unintentional swearing! Think duck, truck, ship... Any way, one day he called me peedee swy (spelled phonetically) instead of sweetie pie. From then on that was the nickname he called me. Not too exciting, but there it is.
