Shandris Brain

A mental condition where one grows up in an environment with virtually zero competition or adversity and gains a false sense of confidence and achievement that stunts their mental development for life. The safety found in living above incredibly low standards is at first a comfort but becomes a dependence. Once shandris brain has fully developed a patient will reject most forms of self improvement and seek environments that reinforce their delusions of grandeur.

Person 1: "I can't believe him! He refuses to accept our advice on what to do and continuously does the wrong thing! I don't get it."
Person 2: "Dude he has shandris brain, have patience."
Person 1: "I'm sorry, I had no idea. I'll be more patient with him in the future."
