Song: Kanye West, Big Sean, Pusha T & 2 Chainz "Mercy"

Sean fires off a number of hot lines on Cruel Summer. Most notably, the hardworking Detroit rapper helps drive “Mercy” to success with some clever wordplay on “ass.”

A breakdown does not have to be technically swift or dramatic; sometimes a simple play on words makes more of a point than a masterpiece. Sean chooses to use the homophone “ass” to replace common words, making a hilarious and catchy list of the many useful functions of a booty. "Mercy" is the right word: Sean is hungry and talented, but relaxed enough to build the verse that made rap critics start taking him seriously on a slice of bouncing booty.
