when a person acts a certain way in one place and acts different in another.

to tell someone to calm down and relax.

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.

two-faced is when someone is nice to you in person but when not in person talks shit behind your back...

Two faced is when someone acts lik your friend and then talkabout u behind your back

When someone acts one way in front of you, but than when your not around has fun ridiculing you

a person that smiles in your face and then turn around and talk bad about you
