ONU f is used as a non-professional shorthand form of the term "Of No Use." It can also be used verbally out loud in public or say in the new normal zoomed out 'office' environment. This, where an inadequate room in your house is permanently used by a corporate entity, without paying rent or compensation of other sorts, simply on the basis that you as a zeeb would otherwise have to shell-out $scrotes to commute to your now obsolete office and back every day of the week.

There is no profanity actually implied nor created from time to time when using ONU! It is a simple three letter acronym and has absolutely nothing to do with the United Nations.
"Yes we interviewed the Gandalf. However, he was ONU, so we sent him for psychiatric reassessment" said the middle manger while stirring his coffee.

"The diodes in all receivers are 1N914's matched on an ohmmeter. (this is ONU and as such should be substituted for Schottky diodes)" from a open source hardware documentation template.
