Refers to the natural direction that the tit and nipple face when hanging or sloughed in a bra. Ultimately the titties will face opposite directions, as to resemble the independent eye movement of the gecko. This is not a birth or development defect but simply a result of three primary factors: 1)Obesity coupled with little to no exercise or 2) age or 3)many years of "hard livin".

To date, census reports indicate that the highest concentration of "gecko tittied" females are found in the midwestern states.
Whoa, take a look at that bitch, those nips are all over the place! Been awhile since I've seen a good pair of gecko titties.
