The greatest example of the attitude I am describing is the French flâneur.
Flâneur literally means stroller or idler, and, in the nineteenth
century, came to describe an elegant kind of gentlemanly moocher, who
ambled purposelessly through the Parisian arcades, watching, waiting,
hanging around. His hero was Baudelaire, as an anti-bourgeois who had
somehow freed himself from wage slavery and was at liberty to wander thestreets with no particular place to go.
I don't know about the mooching.
