re: What is the origin of the "live in your parents' basement" joke?

Millennials finished high school, went to college to get a degree for which there is no jobs available or low pay, move back home to basements up north or old bedrooms down south, and then sponge off of their parents to live and pay back massive amounts of loans that they accrued while getting a degree for which there were no jobs or low pay. BTW, many can find jobs but are too proud to take jobs out of their field of expertise or pay very little.

It's not always the basement but that's more fun for us to say.
