True Story: My husband and I call each other “pump”, “pumpies”, “pumpers”, “Pumpy river love”, or some version there of. It started some 8 years ago when he used to tell me he loved me like rivers. And I was a sweet pumpkin, snackle toothed… whatever. Am still not sure if it is a term of endearment. None the less it stayed.
From this post forward, husband will be known as “Pump”.
