[Col. Thatcher R.] Cardon’s two-part design hinged on a machine he called the perineal access port. This access port would cover an area of the astronaut called the perineum, the crotch zone below the tailbone and frontward, occasionally described as the “fig leaf area.” The port was two flaps and a tiny valve — essentially, a small airlock to expel waste from the suit without losing precious oxygen supply....I love Cardon's nose for accuracy. After he used the colloquial expression "for lack of a better term," he had to acknowledge that technically there is a better term, but it's a technical term, and he won't expect us losers to keep up with his explanation if he uses what are — to a man like him — the best words.
To get from the biological business end through the weenie airlock and into space, Cardon devised a second class of devices he called introducers. One introducer was “a device that rides in the butt-crack, for lack of a better term,” Cardon said. (Medically speaking, he added, that term for the butt groove is the “gluteal cleft.”) The “hygiene wand” was fabric bunched below the perineum that would reveal fresh layers when tugged. But introducers could take any of several forms, such as gender-specific urinary catheters to suck up urine.
And I don't think the term "fig leaf area" has — or should have — much currency. I searched for it (in quotes) with Google, and I had to bypass the first 5 hits just to get to very minor writings like these 3:
And I bet that once I publish this post, I will be able to correct the previous sentence to read "I had to bypass the first 6 hits...."
AND: "the weenie airlock"???
