Most People Assume Something ElseMy username is actually what my nickname used to be as a teenager. The coccyx is the last four fused vertebrae of your spine, also called your butt bone. So, in short my username is a polite, if not confusing way of saying little a$$. Starting at about 14 my parents started calling me little a$$ more often then they did any thing else. I admit that I had a very smart mouth and it took me several years to learn when to keep it shut.
I have found that because of how coccyx sounds when you try to pronounce it most people assume that it has a sexual meaning. No one ever asks, they just make assumptions.
