This is the illusion the majority of basic girls on Instagram and Tinder create in their pictures to make it appear as if they have a phat ass. Generally these girls will bend their bodies close to a 90 degree angle (practically breaking their back) or stick one of their legs out to achieve this illusion. They also will only take pictures from the side or from any other strange angle that can create such an illusion.
John: Dude, this chick looks hot as hell. Look at her ass! I should definitely swipe right
Brad: No, swipe left. She only took pics from side and she’s bending in all her pictures. She has an illusory phat ass
