MudBlood

It's meaning is Dirty Blood. It is a Slur in the Wizarding world. Common used by pure-blood supremacists such as the malfoys, Blacks and Death Eaters. (obviously there are exceptions such as Andromeda Black which married Ted Tonks who is NOT pureblood. Another common exception is the famous marauder Sirius Black)
