A portmanteau of faux and sober to refer to someone who is so drunk they think they are perfectly sober.
Did you see Kelli last night? She was drunk of her ass at her house, but felt that she was fine to drive herself home! She was so fauxber!

The act of pretending to be sober in the presence of authority when, in fact, you're shitfaced.
When we heard campus security outside the door we fauxbered up real quick, and hid the bottles under my bed.
