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.
*Alex and Nick have sex in Alex's room*
During
intercourse they hear the footsteps of the parents. They rush to put clothes on and Alex puts her thong on backwards.
Nick:
That was a close one!
Your dad almost caught us.
Alex: I know, that was really scary. So scary I didn't even realize that I put my thong on backwards.
Nick: OH NOOOO! DID you just give yourself dinglecrackas?
