KonMari

/ˌkɒnməˈriː/

Common

Marie Kondo's decluttering method, or the act of sorting possessions by whether they 'spark joy'. Used both formally and casually to mean a ruthless tidying session.

In casual usage, 'KonMari-ing' your closet or room just means decluttering aggressively, even if the person has never read Kondo's book or followed the actual method.
