A BOUND NAME is a nickname of sorts issued to a person referencing certain characteristics or identifiers about them; the person is then identified by the “bound name” especially by certain groups. This is often done with a negative connotation as a means to belittle or even bully someone.
I don't know his name, we just call him Shaggy; that's his bound name because he looks like Shaggy from Scooby Doo.
