When someone who is familiar in your home knocks briefly and then walks in without being formally invited.
Knocks and walks - to knock on the door and enter immediately.
The guy upstairs knocks-and-walks into our home anytime he feels like it. He just goes ahead and comes right in without waiting for "who's there" or "come in" or "coming!"
