Shotgun wedding

[1] The phrase comes from the figurative imagining that the relatives of the pregnant bride threaten the reluctant male groom with a shotgun in order to ensure that he marries the woman.

In some societies, the stigma attached to pregnancy out of wedlock can be enormous, and coercive means (in spite of the legal defense of undue influence) for gaining recourse are often seen as the prospective father-in-law's "right".

Often, a couple will arrange a shotgun wedding without explicit outside encouragement, and some religious groups consider it a moral imperative to marry in that situation.

This is because they are not recognised as a regular social phenomenon and because a successfully conducted Middle Eastern shotgun wedding is generally unknown to the guests.

In some Persian Gulf nations, the term "police station marriage" (Arabic: زواج مخفر) may be the closest colloquial analogue for the concept of a "shotgun wedding".

Marriages preceded by pregnancy by age in Japan (2010).
This 1897 political cartoon portrays the U.S. annexation of Hawaii as "Another shotgun wedding, with neither party willing".
