Kaiser
Kaiser: a humoristic title for a very rich and succesful person that is extremely extravagant (like an emperor of an empire), naming shaming and claiming the world, the universe and beyond. Comparable to the title of being the biggest boss that you´ve seen thus far.
John became a very succesful international entrepreneur after he graduated from Harvard Business School and during his extremely extravagant 30th bithday party the girls called him Kaiser.
