The idiom "elephant in the room" is not as common as the idiom "800-pound gorilla in the room", but both have similar connotations. The "elephant" applies to some dominant element, situation, or eventuality that everyone is aware of but that is either ignored or barely acknowledged. For example, shareholders at a meeting could be discussing the fine points of a merger, knowing all too well that the government was threatening to shut down the operations of one of the companies involved. An example sentence : "The elephant in the room at the teacher's conference was the new mayor's promise to remove inefficient teachers." (see the related question)
Kitty corner, which is used in the U.S. to mean diagonally opposite is a corruption of cater-corner. Cater itself is an obsolete word meaning four. Compare the french quatre.

No. This is not an idiom. An idiom is a group of words whose meaning is different from the meanings of the individual words. So it is not easy to know the meaning of an idiom. For example 'Let the cat out of the bag' is an idiom meaning to tell a secret by mistake. The meaning has nothing to do with cats or bags. "Treat others like you would want them to treat you" is a saying,
Teasing you .
