back flaps

Fat folds found on obese women where shoulder blades are normally.

The roll of fat that forms on the back of a middle aged friend. This object is usually a surprise if you have not seen the guy in a number of years. The flab tends to look like a "flap", that if opened, might have the ability to absorb a double cheesburger (much like the Venus Flytrap). Although embarrassed, the friend knows that since he has "given up", no possibility for losing the flap exists.
