Faking a text when you're alone, when in reality, you have no one to text. Fauxting is mostly done by teenagers when they are in the presence of other teenagers they dont know.
Boy 1: Dude, I heard your ex was at that party last night, what happened?
Boy 2: Ahh I didnt talk to her. I just was fauxting until she left.
Boy 1: Smart move, you probably looked so cool.
