In kinship terminology, a cousin is a relative with whom a person shares one or more common ancestors. The term is rarely used when referring to a relative in an immediate family in which there is a more specific term (e.g., mother, father, sister, brother, etc.). The term "blood relative" can be used synonymously and establishes the existence of a genetic link.

Systems of "degrees" and "removals" are used in the English-speaking world to describe the relationship between two cousins and the ancestor they have in common. Various governmental entities have established systems for legal use that can handle kinships with common ancestors existing any number of generations in the past, though common usage often eliminates the degrees and removals and refers to people with common ancestry as simply "cousins" or "distant cousin".

By extension, the term "cousin" can also be used when referring to the genetic relationships between humans and any other form of life, as per the theory of evolution of all life on Earth descending from one common ancestor. However, the term in this sense is most commonly restricted to the fields of study surrounding ecological genetics.

Aquille Carr (born 28 September 1993 in Baltimore, Maryland) is an American high-school basketball player. As of 2011, he attends Patterson Senior High School, where he plays as a point guard. Carr has been described as one of the most explosive scorers in the United States and is a scouted prospect for the 2013 college recruiting class. In January 2012 he confirmed, via Twitter, his commitment to the Seton Hall University Pirates men's basketball team for the 2013–14 season.

A native of Baltimore, Carr is known for his small stature, athleticism, and ball-handling abilities. The Washington Post noted that he is "somewhat generously listed at 5 feet 7, in sneakers, including his hair." As a freshman, he led his Patterson Senior High School team to a 76–62 upset victory over No. 5 Digital Harbor with 20 points, 10 assists, and six steals. For the feat, The Baltimore Sun named him its Boys Athlete of the Week on December 23, 2009. The following week, Carr received the honor again after he scored 15 of his 38-points in the fourth quarter against defending Class 2A state champions, Baltimore City College. Filling in as the starting point guard, he helped Patterson defeat Josh Selby-led Lake Clifton with 39 points and 19 assists. In his freshman season, he averaged 25.5 points, 8.0 assists and 5.3 steals.

Jordan Belfort (born July 9, 1962) is an American author, motivational speaker and former white collar criminal who spent 22 months in jail for offences related to stock market manipulation and running a boiler room. In the 1990s, he founded brokerage firm Stratton Oakmont which functioned as a boiler room, and developed a hard-partying lifestyle, which included a serious drug addiction (namely Quaaludes). The firm also served as inspiration for the 2000 film Boiler Room. As the owner of Stratton Oakmont, he employed over 1000 stockbrokers and was involved in stock issues totalling more than $1 billion, including an equity raising for footwear company Steve Madden Ltd.

Belfort was the final owner the 37m yacht the Nadine (renamed after his second wife) originally built for Coco Chanel which by the time it was sunk had been extended to over 50m. In June 1997, it sank off the east coast of Sardinia. The Italian Special Forces were called to rescue all aboard the vessel - no one was harmed. In his book, Belfort details how he insisted on sailing out in high winds against the advice of his Captain which eventually caused the ship to sink as result of violent waves smashing the foredeck hatch. Features of the Nadine included a helicopter, 8 jetskis and 4 or 5 tenders.
