None of these people on the show except for Kya know what love is.
These people don't fall in love with the person, they fall in love with a picture and play it of like they fell in love with the personality of the person. It's sad jokes and so damn true too. vampirefreaks website was hilarious
But like another poster said in each instance, the people are not just fat THEY ARE ENORMOUS, which basically lives up to the typical online jokes people always make.
