I made the mistake of referring to Erika as "The Wife" not long after we were married, she was in earshot and was not impressed and rightly told me so.
"SWMBO" isn't an issue for her and I also jokingly refer to her as the "Minister for Finance".
"His nibs", I haven't heard that for a long time, thanks for the link drron. "Her indoors", gees that's a long time ago as well, rattles brain to remember from what show it was.
Again this should probably be elsewhere, but does anyone else notice that on the Qantas safety video, "eXit" is pronounced "eGGsit", or is it just me? Annoys me everytime, but I'm just a grump, as my wife keeps telling me.
