Definition & Meaning of "codpiece"

What is a "codpiece"?

A codpiece is a flap or pouch that covers the genital area of men's clothing, typically worn by men during the 15th and 16th centuries. The codpiece started as a simple cloth or leather flap that covered the opening in the front of men's trousers or hose, but evolved into a decorative and sometimes exaggerated piece of clothing. It was often worn by knights and other men of high status as a symbol of masculinity and virility. The codpiece eventually fell out of fashion as men's clothing became less form-fitting and more practical.
