I like to call my beloved wife "Schmoopy Woopy" or "My Sweet Little Pudding of Delight".
My missus is a full-on, committed feminist to the point of reading feminist literature, calling out sexist d1ckheads and never taking a backward step against any sexist a-hole. Yes, my life has changed, but I wouldn't have her any other way. If I do call her the "old ball and chain", SWMBO, "trouble and strife" or minister for ..., it doesn't matter. She knows what's in my heart and your ( all of youse) old girl is probably the same. If not, I just withhold her dose of the hot beef injection until she falls back in line.
