That’s how we used to call it, back in the housing projects in my youth. We’d say, “That’s my car” or “That’s my house” when we saw something particularly snappy.
Like this house, whose description in the Milwaukee Journal-Sentinel says:
Secret passages: One, from the media room to the master bedroom
How it works: A section of a built-in bookcase is a door set on vertical piano hinges, which keep it upright as it rolls open on casters. The media room sees a bookcase, and the bedroom sees a door.
The next section is “Why?” but I think anyone in Generation X or later comes with an implied because it’s cool.
