This is a phrase someone in my family used to pull out (I think my dad), but when I searched, I got nothing on this site. It googles, but I thought I'd ask y'all first: sufficiently suffonsified. Look familiar to anyone? Thanks! :0)

the worthless word for the day is: suffonsified

[perhaps a blend of sufficiency and fancified]
(also sophonsified, suffancified, suronsified, etc.)
used in phrases to politely refuse more food at
a meal: full

"The most common line seems to be, "My sufficiency
has been suffonsified and any more would be
superfluous." - Warren Clements, The Globe and Mail
(Toronto) Nov. 27, 2002

"After we've finished our hamburgers and fries she
turns to the boys and says brightly, "Are you
sufficiently sophonsified?" and they gape at her.
They are not the kind of boys who would have
napkin rings." - Margaret Atwood, Cat's Eye

Quinion's take:

You're showing your age: napkin rings???

you may have made a lucky guess about my age; but my name isn't Margaret Atwood.
