I heard someone spell out /usr once, still haven’t fully recovered.

EDIT forgot about bin pronounced bine (rhymes with pine)

How about lib? I’ve heard that one commonly pronounced as lib in liberal would be, but one coworker said it like the lib in library would be, which makes more sense but sounds bizarre!

Lib is short for library in every day speech, as well, and pronounced "lib" not "lyb".
