flâneur (noun) 

A flâneur (flah-NUR) is an idle man-about-town; a casual wanderer and observer of street life. Example from the Norton Museum of Art website: “From the 19th-century flâneur… to today’s social media networkers, the need to get a glimpse of famous or notorious personalities and the compulsion to be seen within an aura of celebrity and influence has driven – and been driven by – the graphic arts.”
