v. When a person, typically a male youth, overcompensates for low socioeconomic status by listening to hard rock or rap and getting tattoos, attempting to portray himself as an alpha male, when in fact he is subservient in the business world due to his poor education and low IQ. He is, in essence, socially and economically subservient, despite his outward rebellion. Hence the phrase: his cheeks are in the air.
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.
