an insulting term from the Wizarding World of Harry Potter (created by JK Rowling). The term itself means, dirty blood. The insult is directed towards witches or wizards who are Muggle-born, someone with non-magic parents. This term is usually used by haughty pure-bloods, witches or wizards who are of magical descent and consider themselves to be higher up in rank. Such as the Malfoy family. The term Muggle-born is very much preferred to the term 'Mudblood.' Throughout the course of the books discrimination against Muggle-borns or 'Mudbloods" intensifies.
Hermione: Shut up Malfoy!
Draco: How dare you talk to me, filthy little Mudblood.

Hermione: **upset by this retort**

Get the Mudblood mug.
The term used for insulting Muggle-borns or First-Generation witches or wizards. Mudblood is the thing all of the prejudice is based on. Students of Hogwarts seem not to really care about skin color or gender. Instead, it focuses on the bloodline of a witch or wizard. Contrary to popular beliefs, Muggle-borns or Mudbloods are just as good, if not better than Purebloods.
