The duckface selfie is the best known variety of selfie. It is by no means the most common variety, but before the selfie, the duckface wasn't easily identifiable. Once selfies became popular, we realized that when people thought they were making themselves look more like models, they were actually making themselves look like ducks. Though the duckface selfie looks ridiculous, it actually comes from a very sensible place. The most attractive among us, models and actresses, have pouty lips. Short of collagen implants, there is no way to make your lips look more pouty. So, we strain our lips to emulate the puffy lipped beauties of stage and screen. Hence, the duckface selfie.
Remember, all monstrosities begin in a sensible place.
