This is means Destined For Fatness. It is a thin girl who will eventually become fat. The idea is that as the saying goes, when you marry a woman, look at her mom and that's what she'll look like when she gets older. This can also be loosely used to classify a girl that over eats, doe not exercise or does unhealthy things. You can either use DFF or D4 which is a thin girl that will eventually explode into a fatty.
