potty-style

We had Ro's five year old check up the week after his birthday. The papers the doctor gave us about five year old behavior said that they tend to use bad words and other "potty language", meaning anything shocking to say. Our doctor said to ignore it or it would just get worse. About a week later, Ro's "potty style language" really exploded. Fortunately, he doesn't seem to know any real bad words yet. The worst words he can use seem to involve either poop or mud or banana peels. He does these strange rhyming comments on everything. A classic Ro-ism would be "Pat! Splat! You're muddy and flat!!!!"
