CASUAL LEISURE
/ˈkaZHo͞oəl ˈlēZHər/

is immediately, intrinsically rewarding;
and it is a relatively short-lived,
pleasurable activity requiring little
or no special training to enjoy it.
It is fundamentally hedonic;
it is engaged in for the significant level
of pure enjoyment, or pleasure, found there.
It is also the classificatory home of much
of the deviant leisure.

In broad, colloquial language casual leisure,
hedonic as it is, could serve as the scientific term
for doing what comes naturally.
