If you are reading this and want to know exactly what a RubbaUndiesLuva is...you're in for some fun. Let me start with a quick introduction. I'm a stay-at-home mom with one little boy. For most of the time I'm a fairly normal lady, but when I talk to a certain friend of mine....I switch from normal to crazy. When we were younger we loved to pretend. We'd pretend we had families and mansions, cars, animals, and our favorite thing to pretend was that we were wearing GIANT invisible Rubber underwear.
