A dinglecracka is when a boy and a girl have sex in their parents home when the house is empty. The lights go off and her shit-covered thong is left on the floor. When they hear a noise downstairs, they scramble to put clothes on. Since the lights are off, the girl puts the shit-covered thong on backwards. Therefore, the shit-covered thong is sucked into the vagina crack; aka the dinglecracka.
