The people are used to living outside in the surf and sun and become pathologically claustrophobic.
To alleviate stress, the indigenous people smash household items they have made many of for this purpose.
During the Smashing Time, one can smash their fill of clay pots, jars, plates and ukuleles. Some of the ukuleles must be put away because they are the equivalent of the Stradivarius violins from better times.
Then the smashing may begin.
Word is claustrophobic.
