I, Wabenzi, by Rafi Zabor

“While trying to nose his battered gray Chevy into a parking space on the Lower East Side, Zabor had a confrontation with yuppies in a fancy new Mercedes. Shouting in a voice ‘full of a barbarian and pure Brooklyn savagery,’ he scared them off, an ‘embodiment of urban yawp and slumland fury thrust out a car window.’ Describing the incident to a friend, he learns that in Africa people who drive Mercedes are called Wabenzi, a compound derived from the addition of ‘wa’ (which means ‘people of’) to Benz (’the characteristic they’d like to be known by’) and ‘i’ for the plural (as in Watusi — ‘the people of Tus’). Much later, when Zabor decides to buy a junky old Mercedes to drive on a soul-searching trip to Turkey, he realizes he may himself become a hated Wabenzi. He is determined that this possiblity will not remain unexamined.”

We may generalize this construction. For example, Wablogi (those who blog).
