I didn't refer to my godson as my godson until I heard one of his parents do it first. They asked me to be a baptismal sponsor but didn't use godparenting language at first, so I wasn't sure what name(s) they were giving the relationship. I was glad when, just before the baptism, the baby's mother said to him, "These are your godparents!" It's pretty awkward calling a kid your "baptismal sponsee." Really drains the cute right out of the moment.
