My best guess, assuming I heard correctly, is "android" but so is she an android. Although the term is not used at all - of course the term used throughout is "replicant."
The other idea is that this is a sort of a compliment, as in "A Team" but I sure don't find that compelling. It could be an insult but I don't think she means to obviously insult him and in fact she likes him, it seems like and is frustrated by his profound indifference.
Grasping at straws: "Alone" boy?
