As I’ve said on this Board in the past, Physics terminology is obscene:

From Dr 90210:
Nasal-labial fold.
The wrinkle from the corner of your nose to the ends of your lip, makes perfect sense , but still.
Although the words below are mostly made up and totally innocent, this whole song just sounds dirty.
*Joe, he was a young cordwangler,
Munging greebles he did go,
And he loved a bogler’s daughter
By the name of Chiswick Flo.
Vain she was and like a grusset
Though her gander parts were fine,
But she sneered at his cordwangle
As it hung upon the line.
So he stole a woggler’s mooly
For to make a wedding ring,
But the Bow Street Runners caught him
And the judge said “He will swing.”
Oh, they hung him by the postern,
Nailed his mooly to the fence
For to warn all young cordwanglers
That it was a grave offence.
There’s a moral to this story,
Though your cordwangle be poor,
Keep your hands off other’s moolies,
For it is against the law. *
The above is taken from the 60’s BBC radio programme “Round The Horn”. Each week a similar song was sung by a character called Rambling Sid Rumpo, played by Kenneth Williams
Flocculent.
Ficus.
Which, incidentally, is my favorite type of tree.
Sure. I have a pendulous ball-sac.
You’re welcome for the imagery.
My alltime favorite Foxworthy joke: If you think a Volvo is a part of a woman’s anatomy…
It was accompanied by an illustration of a redneck guy looking incredulously at his wife, saying “You paid $500 for a used WHAT?”
Lake Titicaca
Gloat.
I don’t know why. That word always sounds dirty to me.
How about Balzac?
Seaman’s Certificate of Continuous Discharge
(This is the document that I had to carry when working on a freighter, and which was used to let me on and off the ship on both sides of the Canadian/USA boarder without going through customs)
Especially the way Hermione Gingold pronounced it in The Music Man
You know how the words up in the corner of the Scrabble dictionary, that show you where you are, really stick in your brain?
AFFLATUS
Ah, imagine my parents’ suprise, when as I was reading a book on a family car-trip at about age 12, I ask “Mom, what does ‘ejaculate’ mean?” :o She very carefully asked me how it was being used in the book, and then said it meant “spit something out”. 
Nipples
Stamen and pistil. I guess they both are dirty, in a way (or at least sexual in nature), but they make me blush for more than they should.
Probe.
Try saying that ten times fast.
(I laughed so hard when I read that, too - I need to stop reading the Dope at work)

Caucus.
Incidentally, at our last federal convention, we had the largest meeting of LGBT delegates we had ever had. The jokes about the “huge gay caucus” were endless.
Most of the girls I knew in college spit it out, too.
