Hoochie is an impolite word, and coochie is an impolite word, but hoochie-coochie is a just fine thing to say. How in the world did that happen? Are there any other instances like that? Usually compounding impolite words makes an even-worse word, like how you can say "ass" and you can say "hole" but you better not put them together. For some reason, this doesn't apply to "hoochie-coochie," which is something you could talk about with your grandmother. Weird.
