From Wikipedia
The practice of taqaandan (also taghaandan) also puts men at risk of penile fracture. Taqaandan, which comes from a Kurdish word meaning "to click," involves bending the top part of the erect penis while holding the lower part of the shaft in place, until a click is heard and felt. Taqaandan is said to be painless and has been compared to cracking one's knuckles, but the practice of taqaandan has led to an increase in the prevalence of penile fractures in western Iran.
