Has 'Me and whoever' long become acceptable usage in informal speech?
In the comments on this answer on ELL, I corrected the usage of "me" instead of "I".
"My boyfriend and I.. " 😁
However, the original answerer1 claimed:
in informal speech 'Me and whoever'2 has long become acceptable usage. I think we've gotten over that one now :)
Fumblefingers is "fairly relaxed about such things" as they mention here, however a sample size of 1 is not really authoritative. Most other answers I found both on ELU and other arbitrary Google searches seem quite set on upholding this rule rather than relaxing it.
This ngram seems to claim the opposite. The "correct usage" seems to be growing.
Is the ngram biased as its corpus is published works and probably less informal?
Have we really got over it? It seems that there are a good deal of people who are resistant to the change in my quick search but maybe I'm not looking in the right places.
1. A clumsy word to my ears, but apparently a real one
2. I'm dying to change this to "me and whomever"!
