A theory, which is proven, that when Phillip penetrates a person(man or woman), the person gains a large amount of weight. The reason behind this gain has not yet been found. Some believe that a part of him combines with their DNA and his gluttony and obesity is passed to them. While many believe simply that the person becomes so depressed from having been penetrated by Phillip, therefore leading to the weight gain.
"Damn Tristan gained a lot of weight."
"Yeah, Phillip and him went drinking the other night."
"Ah, so the Phillip Injection Theory must be true."
