A/N: okay this just came to me… like all my other stories…
Misophobic.
Mudblood: a derogatory term for a Muggle-born wizard or witch; that is, individuals with no Wizarding parents or grandparents. There does not appear to be any difference in the magical power of Muggle-borns compared to those who are pure-blood or half-blood, but those prejudiced against Muggle-borns consider them to be of "lower breeding" or worth, and undeserving of magic. The term implies that the individual has "dirty blood".
He called her that again.
"No one asked your opinion, you filthy little Mudblood,"
That was the first time she heard it. You could even say it drove her to this… obsession.
She knew she was being ridiculous. Her blood was the same as everyone else's.
Then why did she feel this dirty? Like she was never clean enough. No matter what.
Every time he called her that she would flip him off and act like it didn't hurt her; but in reality, it did. It drove her to this compulsion.
Those tiny scratches on her hands where the soap stung. Those hours spent in the bathrooms scrubbing at her hands, her arm, any part of her body. All those cleaning spells she had discovered in her third year.
