It is the face that a girl makes when you do one of two things
A. Do something that is very kind and they didn't expect it.
B. You make fun of them and they don't really mind.

The face it's self is a slight tilting of the head to the side, the eyebrows arch in and a covering of the lower teeth by the bottom lip. The main distinction between A. and B. is that A. is followed by a short,"Aww." Whereas B. is followed by a coughing sound.

The expression on a woman's face when she is severely pissed off.

A girl that loves to suck cock for the sole purpose and grand pleasure of taking it in the face.

A youthful girl who wears a Northface jacket...every day. She has a choppy strand of bangs that covers her eye. She wears jeans tucked into Ugg boots. On any university campus, you can count hundreds of her in one sitting. She could be really pretty sometimes, if she put any effort into having a personality.

the cute girl that is kinda innocent but people low-key want to get with

This is to do with Wilbur Soot's 'I'm In Love With An E-Girl', an absolute classic.
