A ho-bitch who is a total fake and an emo. She is a slut and lies to everyone so she can be their friend. Reillys are also obnoxious and think that they are so hot and pretty. These sluts also hang out with other sluts and try to get their normal friends to be sluts. And they are racist too. If I were you, I would slap a Reilly in the face.
That slut is such a Reilly.
Get the Reilly mug.
