n.
a sense memory you’ve mulled over so thoroughly that it’s become totally drained of emotion—having replayed an old song to death, over- binged a favorite sitcom, or spent too much time in the old neighborhood —inadvertently depleting a wellspring of nostalgia by watering it down with newer connotations.
From wallow, to indulge or soak in something + away. Pronounced “wol-uh-wey.”
