The Boston crab is a professional wrestling hold that typically starts with the opponent lying supine on the mat, with the wrestler standing and facing them. It is a type of spinal lock where the wrestler hooks each of the opponent’s legs in one of his arms, and then turns the opponent face-down, stepping over him in the process. The final position has the wrestler in a semi-sitting position and facing away from his opponent, with the opponent’s back and legs bent back toward his face being very careful not to follow through. This often sees the attacking wrestler perform double leg takedown.

The original name for the maneuver was the backbreaker, before that term became known for its current usage. In modern wrestling, the Boston crab is not treated as a lethal submission maneuver, even though it was considered a match-ending hold in the past. In Japan, it is commonly used as a hold to defeat young and inexperienced wrestlers; the ability to overcome the hold is considered a sign of growth.

Boston (pronounced /ˈbɒstən/ or locally /ˈbɔstən/ ( listen)) is the capital of and largest city in Massachusetts, and is one of the oldest cities in the United States. The largest city in New England, Boston is regarded as the unofficial "Capital of New England" for its economic and cultural impact on the entire New England region. The city proper, covering only 48.43 square miles, had a population of 617,594 according to the 2010 U.S. Census. Boston is also the anchor of a substantially larger metropolitan area called Greater Boston, home to 4.5 million people and the tenth-largest metropolitan area in the country. Greater Boston as a commuting region is home to 7.6 million people, making it the fifth-largest Combined Statistical Area in the United States.

In 1630, Puritan colonists from England founded the city on the Shawmut Peninsula. During the late 18th century, Boston was the location of several major events during the American Revolution, including the Boston Massacre and the Boston Tea Party. Several early battles of the American Revolution, such as the Battle of Bunker Hill and the Siege of Boston, occurred within the city and surrounding areas. Through land reclamation and municipal annexation, Boston has expanded beyond the peninsula. After American independence was attained Boston became a major shipping port and manufacturing center, and its rich history now helps attract many tourists, with Faneuil Hall alone attracting over 20 million every year. The city was the site of several firsts, including America's first public school, Boston Latin School (1635), and the first subway system in the United States (1897).

Patricia Schroeder (born January 23, 1960) is a semi-retired professional wrestler, better known by her ring name Leilani Kai. She began training with The Fabulous Moolah right after finishing high school. In the 1980s, as part of the World Wrestling Federation (WWF)'s Rock 'n' Wrestling Connection, a storyline that combined wrestling and music, Kai defeated Wendi Richter to become the WWF Women's Champion. Kai, however, lost the title at the inaugural WrestleMania event. She was later paired with Judy Martin, in a tag team that would become known as The Glamour Girls. The team held the WWF Women's Tag Team Championship twice and the LPWA Tag Team Championship once. In her later career, Kai returned briefly to the WWF in 1994, challenging for the Women's Championship at WrestleMania X. She also wrestled for World Championship Wrestling under the name Patty Stonegrinder and held the NWA World Women's Championship.

Schroeder was trained by The Fabulous Moolah in 1975 right after she finished high school. She was originally from Florida, but because Moolah thought she looked a little bit Hawaiian, Schroeder was given the ring name Leilani Kai. Her fellow wrestlers also bestowed upon her the nickname "The Hawaiian Princess" during her early career. It was in 1979, that Kai first began working with Judy Martin, who would be her future tag team partner.
