A closet or room in your house where you put everything you don't know what do with; just crammed with stuff, and very messy. From the TV show "Friends". The character Monica was an obsessive neat-freak, but it was revealed in one episode that in fact she had a closet stuffed completely full of junk.
"Don't open that door! It's my Monica closet."
