Crotchamajiggers
Little critters or other unwanted crotch hitchhikers that are transmitted from sodomizing farm animals. Often found in Amish communities, but never officially recognized as a form of recreation.
Jedidiah scratched his crotch fiercely. He noticed Noah looking at him and the goat. Noah screamed across the pasture, "son, youse got yoself a bad case of the crotchamajiggers. Next time you're in town, grab the shampoo and don't tell your mom."
