Having a false or misleading appearance.

You’re fake, and you know it.  You don’t even care that everyone knows it.

I don’t have a problem with people are always angry or disinterested in me, I just don’t have the time for them, but the ones who are make-me-want-to-vomit type nice one day and turn into a complete mole the next really piss me off.

Make up your mind on whether you like me or not.  I’m not going to entertain your multiple personalities any longer.
