Just an anecdotal experience, but yes, I did happen to say things like "this lookup is O(n^2), you should use some other structure here". It's useful when that conversation ends with an "OK", rather than a wide eyes stare...
It just takes less time when you can explain something using common terms, rather than starting with what complexity is.
However most unreasonable cases are much less subtle than that - I run into "filter in the database, not in the app" more often than more complicated issues.
