I guess you could call the backstraps "rib eye" or "prime rib", like the same location on a beef, but they're so much smaller it doesn't seem right.
It's like how we don't cut a venison tenderloin across the grain and call it filet mignon.
That was years ago, though, that "backstrap" presented me with any problem.
But seriously, if a word's commonly spoken, but not commonly written, it should be no wonder the deaf struggle with vocabulary (but as there's nothing one can do about it, no one should worry overmuch about it).
When I was an aspiring writer (this was eons ago), one of my professors noticed a peculiarity about my writing--rather than simply writing the name of something (say, "bridge"), I tended to describe its appearance ("a long road crossing an expanse of water") or its function ("on which traffic passes to cross the river"), because I'd never heard the word, or encountered it often enough in written matter to bother remembering it.
And lo, these many years later, my mechanic, of all people, appreciates the habit. Most people tell him what's wrong, and name parts.....and get it all wrong. I simply describe the appearance and function of the object without naming it.....and after thirteen years, while he's caught me being a little off at times, he's never caught me being totally wrong.
But that's something one just has to live with. However, I'm still irked the time the Treasonous Bastard primitive called me an idiot because I didn't know what a certain cooking appliance was--a primitive used a brand-name for it.....a name that's commonly uttered, but rarely if ever written, and as I'd never heard it before, I had no idea what it was.
Every time I see the Treasonous Bastard primitive on Skins's island, I have to suppress the desire to kick him in the ass; being "socially sensitive" to the problems of the "handicapped," he should've
known I'd never heard the word, and the primitive who originally used it, should've written "electric turkey roaster" instead.
<<<holds the primitives to a higher standard because they allege themselves to be more socially sensitive than we are. (Of course, I find the opposite is actually the true case.)
