In one of Kanye's best interviews (with Tim Westwood in 2005), he says "I'm like a machine; I'm a robot. You cannot offend a robot! You know what I'm saying? Mentally, I'm so focused, there's nothing anyone can say or do to me to stop the music and the product that I'm gonna put out. And at the end of the day, the talent will overcome anything." Enough said.
Best used when: Letting someone know you're indestructible and immune to the haters
