Why do people think its attractive to "duck face"
Because they want attention. I think people should just be natural or do other funny faces lol :)
It may be because they find other people attractive when doing it and they think that they also look nice doing the duck face. However, some people look nice when they duck face while others do not making them look strange; especially in photos.
It's not a-tractive it's un-attractive
they just look ridiculous!
