A layer of buttery cheese commonly found on a sorostitute's back, just above her waist that usually shows signs of dunlap disease and may or may not be accompanied by a large stripper tattoo. This type of fatback is mostly caused from drinking beer and eating large pizzas all by themselves. Possibly a major portion of their freshman fifteen.
Damn, that sorostitute has a serious case of the fatback!!

A person with a giant back, but an incredibly small penis. To make up for insecurities resulting from a case of babydick, a fat back will overcompensate and take advantage of any oppurtunity to brag about his or her hugeness, back or otherwise.
