A nice thing to say to someone, but at the same time, slightly racist. Usually used for black people because, let's face it, they're pretty athletic.
"Man Daryl is so fast, and good at jumping, and basketball."
"Probably because he's black."
"God Ho-Chin-Maow-Lee-Ciao got 100% on the math test! I think he's Asian"
"Good thing I copied off of him."
