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.
