[Ads-l] no duh (1979)

[Ben Zimmer]

The sarcastic expression "no duh" has come up a few times on the list over
the years. Back in 2006, John Baker found it in a 1988 Usenet post and a
1990 news article:

Here it is from 1979, in a glossary of teen slang:

No duh -- sarcastic retort meaning you've just said something dumb,
something obvious to everyone else and there was no need for you to say it
in the first place. Examples: "You're late." "No duh!" or "It's dark." "No
duh!"
