We have 2 shower heads in our shower, one that is affixed to the wall and one that is like a hose, that we use mostly to wash Wrigs. I'm in the shower using the hose (I didn't want to wash my hair) and Tom walks in the bathroom to see me rinsing. He says, "Why are you using Wrig's shower?" I tell him that I'm just washing my unmentionables and I don't need a full on shower. He says "Oh, a whore's bath."
Thank you Gregg (Karen's husband). We use the term quite a bit in this house.
