Quadragon 

A quadragon is a four-sided polygon. There are three words in English that mean the same thing: quadrangle, quadragon, and quadrilateral. Quadragon literally means four angles as does quadrangle. Quadrilateral literally means four sides. Some quadragons have special properties and special names: parallelograms, rectangles, rhombuses, squares, trapezoids, and kites, for example.

Polygon ABCD is a quadragon.

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.
