blue blood

Translated from the old Spanish phrase "sangre azul", blue blood derives from the Medieval belief in Europe (among other places) that the blood of the royalty and nobility was blue; since the royal family and aristocrats were wealthy and powerful enough to pay commoners to labor in the fields for them, their skin was translucent and pale enough for their blue veins to stand out.

It also refers to old money families: families that have been aristocrats for many generations.

The blue blood disdainfully looked upon the unrefined manners of the nouveau riche (aka "new money").

The blue blood of the elite could not be tainted by the blood of commoners, lest the whole line be polluted (disregarding the risks of inbreeding).

Blue Balls 

Blue balls are a very important part of the video games, Sonic the Hedgehog 3, and Sonic & Knuckles. In those games, it is absolutely vital for you to get blue balls. Making sure Sonic gets blue balls is the only way to collect all the chaos emeralds, and access the final level where you regain the master emerald from Dr. Robotnik (who, to obtain it, had presumably spent the entire two games getting blue balls). Getting blue balls is so popular that Sega decided to include it as a hidden bonus in Sonic & Knuckles. Connecting that game to the original Sonic the Hedgehog grants access to a mini game with 134,217,728 randomly generated levels (constructed from predefined chunks of level), allowing a player to endlessly get blue balls. For some unknown reason, the original title text of this level, "GET BLUE BALLS", was changed while the game was in beta, to the final release's "GET BLUE SPHERES".

I stayed up all night last night, getting blue balls.

Blue Hat Emoji 

In a similar style to president trumps 2016 red MAGA hat, 2020 presidential candidate Andrew Yang's blue MATH hat has become a symbol of him and his supporters, the YangGang who have started using the blue hat emoji in their twitter usernames to aid in quickly identifying each other.

"Be sure to add the Blue Hat Emoji to your name so everyone'll know your Yang Gang."

Blue dream 

Blue Dream, a sativa-dominant hybrid originating in California. Crossing a Blueberry indica with the sativa Haze, Blue Dream balances full-body relaxation with gentle cerebral invigoration. You'll enjoy the level effects of Blue Dream, it'll ease you gently into a calm euphoria. Some Blue Dream phenotypes express a more indica-like look and feel, but the sativa-leaning variety remains most prevalent. a relatively high THC range that averages at a low of 17% and a high of 24%.

Blue dream is a strain.
