This girl I know asked me if I wanted to hang out sometime. Just"hangout"(she put emphasis on that) What exactly did she mean?

Did she mean maybe a casual date? She is expecting me to call her. And it will most likely just be the two of us.

Emphasising "just hangout" she was making sure you knew it wasnt a date
How can we possibly know if it will be just the 2 of you or not?
