Ernie Special
Where a person is shitting on the toilet and describing it in great detail to their partner who then has to vomit and does so into the lap of the person on the toilet.
A guy was wrapping on the toilet and describing his creamy bowel movement to his girl who had just finished eating, she gagged twice before she couldnt fight it any longer and proceeded to give her guy an Ernie Special and vommited onto his lap.
