One solution is to avoid using the word "scrum". Since nobody can really agree on exactly what it means the word is worse than meaningless. The word serves only as a conversation trap; many good conversations devolve into defining what "scrum" means--somehow we went from a meaningful conversation to endlessly arguing over the definition of a single word.

The polite way to say this is something like "people have many ideas about what scrum is, can you explain what you mean without using the word scrum, it would help my understanding".
