What does the idiomatic-expression 'in the doghouse' mean?

Answer 1

It means that you are in so much trouble that your wife has kicked you out of the house and you have to sleep in the doghouse with the dog. Usually, this is not literally true, but you might be sleeping on the sofa.

It means his wife was mad at him (hence, metaphorically, she kicked him out of the house and he has to sleep in the doghouse).

It means you're in trouble. Example: "Ooooooooh She's In The Dog House Now,"

If you are in the doghouse, or if you are in someone´s doghouse, it means they are angry with you. You have probably done something to make that person angry and face some kind of punishment. Just as if a dog misbehaves, the owner may put him outside in the doghouse.

Answer 2

It's a slang expression that means the man is in big trouble, usually with his wife. It implies that because his wife is angry with him, he will not be allowed into the house, so he may as well sleep where the dog sleeps-- in the doghouse. (This is not a literal expression-- the person using it may not have a dog. But the point is that he is not welcome in the house right now.)
