When you are trying to make fun of someone for being bad at something instead of saying, " you suck" you can instead say," Boi you donkey cheeks!" Therefore implying you are so ass at something you are ass compared to an actual ass's ass.
Boi you are donkey cheeks at touch football you couldn't catch the ball if it were the size of a watermelon.
