Illusory Phat Ass
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.
