bit like syncopation, what?

and not a bit ugsome to my ears...

No, etaoin. More like time I was eating in lab cafeteria with a couple prim ladies
and a brilliant and cultured bacteriologist, who had spent many months in
Astralia during WWII. He said:"Hey Bill, pass me the horsecock" meaning
the sausage. That was a contretemps.

And a faux pas. And a gaffe.

Faux pas and gaffes are more easily forgiven than contretemps.

Depends upon how pas the faux is, wouldn't you say, wwh?

Does Ugolino, from Dante's Divine Comedy, share in this root? It's a proper name to be sure, but it did come from somewhere.

Sounds as though "Ugolino" is "little Ugo" and only a little be ugsome.
