Designation (noun): the act of indicating or identifying.

“Every now and again, I would see him, a burly man with close-cropped graying hair, pushing a shopping cart or sitting at an outside table at the Starbucks on Maryland and Dorothy, sipping from a container of coffee, wearing what looked like a Runnin’ Rebels basketball shirt, slit up the sides all the way to the armpits, with that designation – Facebook president of the world – hand-painted on the back.”

“Walk with Me” – David L Ulin

This honestly was a new one for me as I have always known per say what it meant as if someone was designated as the leader, or as the designated driver that meant they were chosen to do it. However, it has a slightly different meaning as it is more of a choice by your peers rather than yourself.
