hang on a minute, there’s spaces around your em-dash! An AI didn’t write this at all, this is fake AI! I call Shenanigans!

Ok, try complimenting a man on his bosom and see how he reacts.

You might read it that way, but it doesn’t make the other reading wrong the way that user SwingingTheLamp was suggesting.

https://www.collinsdictionary.com/dictionary/portuguese-english/seio has breast as the first translation.
