I'd certainly dispute the "memorable" part for most people on Earth.
You could use this on $LANGUAGE of your choice, or $CORPUS of your choice.
(Also, it seems much more memorable to me than an equivalent random stream of bits are.)
Still, neither "wrowd", nor "aut", nor "settea" looks or sounds English-like to me. I wouldn't even begin to know how to pronounce it.
It's nice in a sense, sure, but I suppose I could even remember (real) French words better, despite all those accents and me not speaking French.
"aut": a logarithmic unit of measurement indicating the level of automation of a process. "I think we can get another couple of auts out of the sentiment-analysis pipeline."
"settea": a genus of shrubs in the family Settaceae.
I frown on casually lying to people over the internet. The term 'OK' originally stood for 'all correct'.

You're trying to allude to NOKD, which is (1) completely unrelated, and (2) not lost.
