When a girl pouts out her lips like the duckface but only pouts them out a little bit, more like a kissy face.
Either way it's still the duckface they're just trying to be sneaky and cute about it.

"Tumblr-girls" tend to do it a lot.
Guy: "Hey this girl looks hot, look at this selfie of her."
Friend: "Nah man she's doing a subtle duckface, that ain't cute."
