Yoga-donk
The cross between a yoga-butt and a donk. A rare type of ass mostly found on ethnic girls who are in very good shape. Asses that are slightly smaller than a donk but still larger than a yoga butt are sometimes called a junior yoga-donk.
Examples: Beyonce (young), Kim Kardashian, Eva Mendez, Vanessa Hudgens, and Jennifer Lopez (young) have yoga-donks.
