I need an explanation for the following saying or idiomatic expression. I heard it the other day and I haven't been able to google a coherent explanation, in fact I saw there were variations to the one I had read which makes it slightly more confusing:
Was schert es die Eiche, wenn sich eine (Wild)sau an ihr schubbert?
Was schert es die Eiche, wenn sich die (Wild)sau an ihr kratzt?
Was schert es die deutsche Eiche, wenn sich die (Wild)sau dran reibt?
Was kümmert es die stolze Eiche, wenn sich die Wildsau an ihr wetzt?
Was kümmert es die Eiche, wenn sich ein....
I can only deduce based on the actual words, that it has something to do with situations in which a stuck-up or haughty person feels disturbed or annoyed by what he/she considers lesser or not worthy of their time thing, person, or idea. But that's it... and not even sure if that is correct (I'm just guessing based on the context that I heard it). How or when is this used, and what does it mean more clearly?
Thank you for elucidating!
