What do you mean, dogs hang themselves?

The phrase "all dogs hang themselves" has no practical significance. It is an exaggerated expression, which is often used to describe something, someone or a situation that makes people very angry, irritable or unbearable.

Usually, what we call "all dogs hang themselves" is an expression of strong feelings, both in practice and figuratively. Whether it is anger, impatience, boredom, disappointment, anxiety, surprise, etc., this word can be used to describe it. In fact, this word is a vivid expression of metaphor, from which we can feel emotional intensity.

It should be noted that this word is not a real "swing", and we need to grasp it according to specific situations when using it. Generally speaking, we think dogs are smart and sensitive, so this expression implies that even what dogs can't stand is even more impossible for humans to stand. But you can just say it casually and don't care too much.
