Someone who is extremely disgusting and oozes lard and grease. Basically extremely unpleasent to look at, these fatfucks tend to migrate towards each other because no one else likes them. Eventually, when they gather in large areas, they perferm oral sex on each other (most fatfucks are girls) but are in reality eating each other because they are so fat. Leah and Haley are fatfucks and no one likes them.
