If not "Two Beers, Officer", then what?

Yes, however you can be detained for 72 hours without being arrested. I don't recommend refusing questions before you are arrested.

Whether you call it an arrest or not, detaining someone for 72 hours requires probable cause that you committed a crime. You can be detained if you refuse to identify yourself (if your state makes that an arrestable offencse), but you cannot be detained for merely refusing to answer questions about how many beers you had.
