Poorgeoisie is referred to a group of people, usually in their 20's, who comes from a good strong middle class family, but claims to be poor and roughly on their own. willing to spend money on high end restaurants and other lifestyle luxuries but refuses take care of their personal hygiene. Most of them don't believe it's important to be so superficial so they usually don't wash their clothes, bathe, or brush their hair. So instead they spend their money on food, movies, concerts, and other lifestyle luxuries. Very similar to Hipsters but not as pretentious.
Casy: What are those girls doing at that restaurant? They look like they can't even afford it.
Julie: Oh, those girls are poorgeoisie. They only spend their money on lifestyle luxuries such as museums and food. They don't believe that you should pay attention to superficial things like clothes or hygiene.
Casy: ok, so "bourgeoisie" but more on a "i just got out of college and am poor" level, but they aren't really poor?
Julie: yeah, a less pretentious hipster.
