Magbob

Magbob is an ancient term for a wizard of Muggle decent, meant to be a term of endearment. The term was popular prior to the formation of the International Statute of Wizarding Secrecy in 1692, in a period which most wizards considered Muggle-borns to be more gifted than wizards of purely magical blood. Following the circumstances that led to the Statue of Secrecy, wizards began to seriously distrust Muggles, pure-blood supremacy became widespread and the term fell out of favour.

Etymology

 * Though there is dispute over the origins of the term, "Magbob" is mostly like a portmanteau of "magic" and "bob", thus implying that a Magbob's magic "bobbed up" out of nowhere.
