Spanish translation pls

Just randomly saw a message on my bfs phone which is in Spanish, I don’t know Spanish all that well but and he was replying to a girls story and I understood it to be something like ‘uuuuyyyy you are the exorcist’

What could he mean by that? I didn’t see what her story was, could be innocent but my minds going crazy what it could be. I don’t want to bring it up with him incase or start a fight but just more curious if anyone knows

Thanks 😬
