What makes a fatty a fatty? I am genuinely interested in what makes a fatty a fatty? Is it strictly body size? Is it body size + mentality? Is it mentality?  I have a sneaking suspicion I might physically be a fatty... and want that to change (exercise and diet yo!). Conversely, if you can't find the words to describe what a fatty is - what is a shining example of a shitlord/healthy person?
