Not really an AIBU, but I wanted a good list! DH and I were talking about words and phrases we used to say frequently as children in the 80s and which now we rarely use or hear. Some of these refer to things that no longer exist, or which have become rare, some have fallen out of fashion, some now seem tasteless or prejudicial. Would love to hear some more! (And doesn’t need to be from the 80s.)
