Adjective for any storage space or container that is expected to continue to hold/store more and more shit in spite of the fact that it’s already FULL (commonly filled with a bunch of useless shit that you no longer need or use but aren’t ready to be rid of yet).

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
