That is SO funny this thread came up! One of my dogs names is Lexi. But for some reason her nickname is PooPoo. I can't even remember how it evolved… Anyways, the other day she curled up right on my tush, as she usually does. It was so cute and before I knew it I had screamed to my husband, "Quick! Take a picture of PooPoo on my butt!" He came in laughing soooooo hard... And of course now it's a running joke!
