Quadrafong

Historically in the context of the Americas, a quadrafong or quarterfong was a person with one quarter asian and three quarters European ancestry. Similar classifications were octofong for one-eighth asian and hexafong for one-sixteenth asian. Most likely considered to be an offensive term.

Eric's grandparents and father are American but his mom is from China, therefore he is a quadrafong.

Quadricos

Also known in certain social circles as "Q," Quadricos has killed 17 people, has a vast collection of bow ties, and occasionally plays backgammon with Fidel Castro.

A Quadricos is not meant to be confused with a "Farbara", who is a total giant fucking cunt.

When confronting a Quadricos, you will initially want to shield your ears as his expansive vocabulary and spot on diction will fucking destroy you.

Quadricos is also technically a shortened version of "hella fucking balls-to-the-wall awesome"

Q: Greetings and Salutations
Regular Mortal: HOLY FUCKING SHIT IN MY BALLS! You're Quadricos.
Q: Yes. Yes I am
Brancisco: At least he's not Farbara
