“Male chauvinist pig” is something many would be very upset to send to their boss by accident. So it’s perhaps understandable some such phrases are not excluded from the guesswork.
We might not talk about a "narrow contingency put" or "Maria crating PVC" very often, but an uncensored autocorrect would almost certainly correct those phrases to the far more common "male chauvinist pig" in the rare cases where someone did try to swipe them.
Step 1: a word of 4-6 letters that's somewhat close to "male". Say "name" or "masked". Look at the key positions, you'll see what I mean.
Step 2: a word that's even less close to chauvinist, and that makes sense after the word you intended, but no sense after "male", so the guesser picks "chauvinist", based on its incorrect first guess and your second swipe.
Step 3: ditto.
The difference matters enough that preemptively suggesting "pig" is not a desirable "service" for most people.
I know these are all typos because she’s a really close friend and easily the last person who would be offensive to other people.
So yes, you’d be surprised at what people can typo on a phone.
