A suffix added to the end of a name of someone who is pompous, pretentious, and otherwise grossly beguiled by their own sense of entitlement, and their given name doesn’t justify their personality enough.
Lauren: I want to talk to your manager, I demand my 72 cents.
Ben: Chill out, it’s not a big deal. You’re being a real Lauren Amadeus Bandersnatch Weissenhaus right now.
The name means "God's Love." Amadeus is a boy who has been gifted with Godly talent only to have the jealous devil taint his soul and deceive the public that he is pure evil. Drugged up and abused to stray him from his true divine destiny.
He is not worthless.
He is not ugly.
He is not meant to be sexually abused.
