Those #@%^%** Cuss Words! Part 2

Body parts as “dirty” words puzzle me. Mores change in most cultures. Certain terminology that had been avoided in polite company is now heard in normal conversation. Some see this as moral decline while others see it as linguistic evolution. I probably fall somewhere in the middle.
Certain parts of our body have at least one euphemism that we tend not to use in mixed company. Some have more. Some of these words have other meanings when used in a different context.
Every square centimeter of our bodies is named and illustrated in anatomy books all over the world; even the “dirty” parts.
Generally speaking, the parts of the body that were given vulgar nicknames are the ones that have to do with sex, or waste elimination. There is one part that isn’t directly related to sex or elimination, but has an association with each. Which one do I mean? You’re probably sitting on it.
Nothing elicited more giggling than Judges 15:15, where Samson slew a thousand Philistines with the jawbone of an ass. Us kids thought that was great. We even started reading the Bible to look for more dirty words.
We could always get away with calling someone an ass.
“I meant the donkey one!” we’d shout.
I don’t know why using that word to describe one’s Gluteal region was deemed vulgar. Today we’ve softened on our stand against that word. We can talk about kicking ones ass (not the donkey) and not be viewed as too uncouth. On the other hand, if we add the word that, combined with ass, is another word for anus, we are considered to be swearing. We can say ass, but a**h*** is still kinda frowned upon in most of our society. “Butthead” doesn’t even get a second glance anymore. Although most of us instruct our children not to say that. I dare you to call someone an “anal orifice” at the top of your lungs and see what kind of looks you get.
Genitalia probably have more nicknames than you could shake a stick at. The penis for some reason was called the nickname of our 37th president. I don’t know why. Another name for it is another name for a rooster. Again, the Bible made us laugh. (Matthew 26:34 King James)
Now, some people get squirmy hearing even the official, anatomical name for the female counterpart. It’s my opinion that the “Big V” has the honor of having the most vulgar word assigned to it. (I never said I was immune from these cultural biases, just that I don’t understand them)
Testicles never seemed to reach swear word status, but we’ve still assigned them lots of nicknames.
The breast (female variety) has a lot of rude nicknames. For some reason, today the term “boobs” is acceptable, while when I was a kid it seemed to be on the same list as the “T Word”. A tit is a bird found in the Northern Hemisphere and Africa. We weren’t allowed to say it. I didn’t get that farmers always talked about teats, which were found on the corresponding location of their cows.

When I was a kid my mom never used the anatomical terms for our naughty  parts. We didn’t have penises or gluteus maximi, we had peepees, tushies, or hineys. Go ahead shout at the guy who cut you off on the onramp “You peepeehead!”  There, didn’t that feel good. “You tushface!”  I’m feeling better already.

I’m not trying to make a case for more swearing on TV, or for letting our children test out George Carlin’s “Seven Words” on their teachers. I just want to know how and why we chose which were the magic, wash-your-mouth-out-with-soap, bad words
