it is the first time i see the word "the duck face pose", but i think i have understood the meaning of this word correctly by trying to imagine the face of a cartoon duck. does it mean "behave in a spoiled manner"? :p
maybe it is easier for people to get close and take care when we try to show we are lower (or weaker) and we love the others and want the others to love or protect us.
I don't know, nor do I want to know, because I don't get it, it makes them look like they're gone inZAYN. ha, get the joke? and it makes them look constipated. I don't care, I'm still never doing that face. never have, and never will.
