Incredibly oversized testicles. Often referred to as Elephantitis.Hey dude, I think I may have Mauricio Syndrome, because my nuts are the size of grapefruits!!

But on the contrary it also means incredibly undersized peenis. Often referred to as small dickitis. It's not very common, and its often a matter of concern, since its heaviest symptom is that your dick starts to dissapear as time goes on. It will eventually dissapear, most of the time this happens while you are screwing, playing with your genitals or in other cases it takes up to 48 hours
