blue blood

From the medieval European belief that royalty and nobility had blue blood; the elite had enough power and wealth that they could afford to have peasants and the urban poor do their dirty work for them- since the aristocrats were able to stay inside and avoid long hours in the fields (and the sunlight), they were often so pale that their blue veins showed under their translucent skin, thus leading people to believe that their blood was blue.

Now it generally refers to people from old money: families who have been wealthy aristocrats for generations on generations.

The blue blood elite have long been discouraged from intermarrying with commoners, lest their pure bloodlines be contaminated, ignoring the degenerative effects of inbreeding.

Blue Friday

Blue Friday is a Seattle Seahawks tradition created a couple years ago where all fans are supposed to wear their favorite Seahawks gear on Fridays to support the team. Originally it was for game day Fridays, but now it's EVERY Friday during the regular season.
