n. The act of rummaging through one's closet for the purpose of getting rid of old, unwanted, or unworn clothing, thus freeing up space.

A closet cleanse is triggered by having way, way too many clothes that have either accumulated due to outgrowth (see clothes hoarder) or being a clothes whore.

One must consider performing a closet cleanse if it takes more than 5 seconds to find one's preferred shirt.
