someone who acts nice to you when you are around them, but the minute you're gone they're bad-mouthing you.
"OMG cameron is so two-faced, when you are with him hes acting like hes your best friend but when your gone hes saying bad things about you and saying he hates you."

A persona that usually stems from a lack of self-identity, self-esteem, and/or cajones. The person is also usually a brown noser, as they try to please whomever they meet. In an effort to be accepted by the entire world, a "two faced" person will socially accomodate anyone they meet in an attempt to be popular and liked by everyone. More often than not, however, two faced bitches are usually covering up their assholism.
Sherry loved to be liked by everyone. There wasn't a person that she didn't meet that she could not be "friends" with. However, when her "friends" weren't around, she was a two faced bitch. "Damn, I fucking hate Janel; she's really a dirty cunt licking whore. Hey, I'm going shopping for Janel's birthday party on Friday, wanna help me pick something out for her?"

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."
