I guess you haven't been around enough to see the sheer numbers of fatties wanting guys who are tall. Like that girl who's like "under 6' don't even talk to me" and the one making a hideous face (even for a fatty) with a caption "the face you make when his height starts with 5' " It's pointing out that even though fatties don't meet any beauty standards and it's something they can change, they choose a measure that people can't control as a standard.  explainingthejoke
