The humblebrag is not a new phenomenon. In fact, people have probably been saying things like "The hardest part about flying first class is I can't stop eating the free nuts!" or "So jealous of people who can walk down the street and not get hit on!" since the dawn of time.
And there's no better forum for the display of the humblebrag than Instagram. Where else can you post a picture of your Louboutins with the caption "My feet are killing me! Brand new heels were a bad decision today" or upload a shot of your beach cabana and lament "So sunburned, I've got to remember sunscreen SMH"?
But, apparently, Justin Bieber has forgotten how the humblebrag works.
