Why do girls make odd faces in their photos on facebook?

[freya]

I am really curious I get on facebook now and all is see are girls making "duck faces", sideways peace signs, or flipping the camera off looking pissed, or we cannot forget the classical photo from above, or the boobs pressed together tightly pose. I do not understand why can't girls take regular photos of themselves?
I mean as a girl myself I think that other girls are the most beautiful when they smile, and it's not fake or posed or anything

Because they are ugly, and think that making faces hides their real (ugly and unphotogenic) face.

Those are the girls you AVOID. It's an attention thing

Girls are weird

Because they're resting face is not attractive so they have to make a face that makes it look like they are not trying look cute or they take a selfie that is in the perfect angle after taking doZens of pics so they look cute

They think its cute but it isn't. Some girls dont do that. They are the ones you should hang out with

They are testing their facial expressions on cam.Or maybe it's for fun-sake

Because they like it lol. This is less of a facebook question and more of a culture question or something. Maybe they think it's pretty. It's like why do you smile for pictures when nothing good is happening, or why do people pose at all?

Down syndrome. That's why they have screwed up faces.
