A multitude of infectuous sexually transmitted diseases (std) that have mutated together that infect the male or female genitalia leaving a number of pus filled blisters and lesions which eventually cause the male's penis to rot and fall off and the female's vagina to appear that it is throwing up a combination of 8 week old spaghetti and cauliflower in a cream sauce. It emits a foul rotten odor that so strong that flies and maggots will not go near it.
