I had no idea my "1/4 black" would raise so much comment. Maybe I had better give you more context.
Pete, Trey, and Dixon are watching the scene in which Trey bottoms for Dixon.
Trey: (watching himself sit on Dixon's cock) "Gettin' on that chocolate! What ethnicity are you?"
Dixon: "I'm three-quarters Caucasian and one-quarter African-American."
Trey: "Looks good on you."
Dixon: "It's a good mix. I like it."
From there they go back to discussing the scene. Pete never said a word on the subject.
My only observation is that mixed race is so common most big cities that it is no longer remarkable at all, just interesting sometimes, as in the case of Trey's question.
