Somebody that lies about every aspect of their life, what they believe in, what they feel, and who they are. Somebody that has an endless amount of false names, not false screen names or something mostly benign, something a bit more malicious, but has many false names in real life and claims each one of them is his/her real name.
The girl was the kind of poser that didn't want anyone to accurately identify her, so she had numerous false names and looked like a different person on the outside almost every time you saw her.
