To say one thing and do another. Also to act one way on saturday, and flip a bitch on tuesday.
"I'm a Two-faced cunt that dosent really know what the hell she wants, please dont mistake my apparent feelings for you as real feelings, even though I tell you they are, cause it is in my nature to say one thing, do another, and claim to have done a third."
i.e M.E.

Someone who has two faces or parts to their personality. Like they'll be all nice to you one second and when you're gone start talking about you behind your back.

Laura: Thx. :)
Mary: Well see you later hun!
Laura: Bye Mary!

*once Laura is gone*

Mary: Ugh, I'm tired of that two-faced bitch.
Stephanie: I know right?
