Why Is Gonorrhea Called the Clap?

Gonorrhea is a common sexually transmitted infection (STI) affecting millions globally each year. While medically known as Neisseria gonorrhoeae, it is widely called “the clap.” Exploring its origins sheds light on how medical conditions were perceived and discussed in earlier times.

Gonorrhea: A Brief Overview

Gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae. It transmits primarily through sexual contact, including vaginal, oral, and anal sex. The bacteria thrive in warm, moist body areas like the urethra, cervix, rectum, throat, and eyes.

Symptoms vary, but common signs in men include painful urination and pus-like discharge from the penis. Women may experience vaginal discharge, painful urination, or bleeding between periods; many women have no symptoms. Untreated gonorrhea can lead to serious complications like pelvic inflammatory disease in women and epididymitis in men, potentially causing infertility.

Unraveling “The Clap”: Historical Origins

The exact origin of “the clap” is not definitively known, but several historical theories offer plausible explanations.

One theory links the term to medieval French brothels, sometimes called “les clapiers” (meaning “rabbit huts” or “burrows”). Due to the association of brothels with STI transmission, “clapier bubo” (inflamed lymph nodes) may have described the disease contracted there, eventually shortened to “the clap.”

Another theory suggests the nickname derives from the Old English word “clappan,” meaning “to beat” or “to throb.” This could refer to the painful, throbbing sensations experienced by individuals with gonorrhea, particularly during urination.

A third theory relates to historical attempts at treating the infection. Before antibiotics, crude methods addressed the discharge. One method involved physically “clapping” or pressing on the penis to expel pus from the urethra. Though ineffective and harmful, this practice may have contributed to the enduring nickname.

Why the Nickname Endured

Despite medical advancements and the formal identification of Neisseria gonorrhoeae, “the clap” has persisted in common language for centuries. Its simplicity and memorability likely played a role in its longevity. Informal language often adopts shorter, more colloquial terms for complex or sensitive subjects.

The historical stigma associated with sexually transmitted infections also contributed to the use of euphemisms. People used indirect or slang terms to discuss STIs, which were linked to perceived immoral behavior. This social stigma made direct discussion of conditions like gonorrhea uncomfortable, fostering less direct phrases like “the clap.” Its widespread adoption in popular culture and informal communication further solidified its place.
