A girl, particularly of the track running variety, who has a massive ass that looks like it should belong to a black woman yet it really belongs to a white girl. A Donk of the Year usually is a 10 in the donk but only about a 7 in the face. The Donk of the Year, along with a HUGE ass, happens to have a particularly fine ass.
Wow. It's a surprise they make spandex that could contain an ass like that since that girl is a "Donk of the Year"
