In Norway we have the stereotypical Norwegians "Ola Nordmann" and "Kari Nordmann". Ola and Kari were quite common names a couple generations ago (not so common now). "Nordmann" literally translates to "Norwegian [person]", but is also a not-too-uncommon last name.
We typically talk about them if we're describing something or some situation and what the stereotypical Norwegian would do/think.
