Or Shaving Private Ryan? Does anyone have any good original ones?
I always heard it as Shaving Ryan’s Privates. It has more zing that way.
My favorite is “The Best Rears of Our Wives”.
“The Load Warrior” had a great Tina Turner-esque theme song. Then there was “Hot Gun,” a fantastic movie about co-ed naval aviators that somehow managed to be filmed without a single airplane (locker rooms, mostly). I understand “Edward Penishands” was quite good as well.
There actually was a video out when I was younger called “Backside to the Future.”
I’ve heard of “Jurrasic Pork” and I’ve actually seen “Rambone”.

– Never made much sense as a name for a military alliance; excellent title for a curiously highbrow porn film!

I seem to recall seeing the titles, “Hannah Does Her Sisters,” and “The Oddest Couple.”

The “Murphy’s Video Express” catalog was a wonderful source of these titles. My friends and I had a three page list (small font) of ideas that we came up with.
My personal favorite was “The French Lieutenant’s Bitch”.
We could do this all week. Have fun.
A Midsummer Night’s Cream
Strictly speaking, this is not an answer to the OP, but one of the most wonderful spoofs of porn movies was It Happened In Hollywood. A Must See.
Beverly Hills Copulator always cracked me up.
