"Meine Ehre heißt Treue" is a phrase that means "My honor is loyalty" in German. It was the motto of the Nazi SS, which was a group of soldiers that were very loyal to Adolf Hitler during World War II.
So, imagine you are part of a club or a team. You want to show that you are a good member of that club or team, and you want people to know that you are loyal to them. That's what this phrase means - it's a way of saying that you are proud to be part of something and that you will always be loyal to that group.
Now, it's important to remember that the SS was a group that did some very bad things during the war, and we don't support their actions or beliefs. But the idea of being loyal to a group or cause can be a good thing - as long as that group or cause is doing good things and treating people with kindness and respect.
