Thai Dick Slug 

An invasive parasite that attacks the kidney systems in carnivorous animals, including 20 documented cases in humans. The parasite has been known to produce larvae in the scrotum, urethra, urine and mouth. Referred to as "Dick slug" because of the minute size of the parasite, with females being 20-100cm long x 5-12mm wide. The dick slug is small enough to meander its way up the urethra.

Don't go swimming in Thailand without a condom. You might get a Thai dick slug.
