Highly idiomatic phrases are always going to be problems for natural language processing. Further, people aren't 100% accurate in language processing either. I'd say that if you posed that statement to 1000 English speakers from around the world, at least 1% of them would be baffled by it. All that is to say non-conventional uses of language are always going to be a problem for natural language processing. If a certain kind of innuendo and sarcasm is represented often in its training data, then the model SHOULD be able to understand it when it sees it again.
