For those of you not familiar with the Harry Potter canon (ahem, pushes up glasses) a mudblood is a wizard of Muggle-born descent
. Still don't know what that means? Then you should probably stop reading, because you're never going to care. Oh, you're still here? Aren't you tenacious. Basically, it's the result of J.K. Rowling trying to jam some political undertones into Harry Potter
and give it a cute name. Anyhoo, there appears to be a Slytherin
alum run amok in San Francisco.
