Three totally different things. People get really confused with these facial expressions.
This thing has been bothering me for forever now.. Relieved that I can finally express this annoyance I'm feeling. Haha
POUT : To protrude the lips in an expression of displeasure or sulkiness.
KISS : The general shape of a face when kissing someone.
DUCK FACE : Pressing one’s lips together into the shape of a duck’s bill.
I hope you guys get to see the pictures clearly and understand what I mean
