Puzzled about this body language mvoement.

Hi everyone. I'm a little bit confused, what exactly this could mean:

One of peoples i know is playing with her lip, before and after saying something. When she is talking, she just moves her hand like 10-20 centimeters from her mouth and moves it, while talking, then again goes back and continue the "game" with her lip. Scrathing it, touching it, or just holding a hand on her lip. Lower lip.

This is a person from authority figures. She often orders my class (i'm a student) to do some crazy things, just because she thinks, that no one else will do it. When doing that, OR when trying to make us believe in some big, big lie, or convincing people to join with her to do something, she often does that. She does that almost always, when talking "business".

Anyway, what that could mean exactly?

she is trying to touch (kinaesthetic) her words (Auditory). she may be feeling how her words will sound.

Yea, that would make sense. She tries to prove something, to convince people and to mess up their minds after all. That's why she tries to touch the audithory.
Thanks.

You sound very suspicious of this female person who plays with her lip. You assume it's a game of hers, you believe you know what she is thinking "just because she thinks no one else will do it". And also acuse her of not just lying but trying to convince you to believe in her lies!
There is a lot going on here. You think you know her motivations for her behaviour yet this one with her lip you can not figure. Touching oneself is a sign that that person craves to be touched. Either unconsciously or consciously that is the message she is projecting with this action. The lips are sensual and touching them is projecting her sexuality. Or it could just be she habitual, a habbit she can't break. I doubt it's auditory, if you are right in your perceptions about her, she sounds like a manipulator therefore will use and experiment with techniques to achieve her desired effect. But again it could be you being cynical & mistrusting, she may be authentic with a bad lib touching habit. See which fits with you best.
