Context paragraphs:
1998–99 Boston Celtics season: The 1998–99 NBA season was the 53rd season for the Boston Celtics in the National Basketball Association.  The Celtics continued to build with youth as they selected Paul Pierce out of the University of Kansas with the tenth pick in the 1998 NBA draft, while acquiring second-year center Tony Battie from the Los Angeles Lakers.  Pierce would get off to a fast start as he was named Rookie of The Month in February, after the season was delayed by a four-month lockout.  However, after a 7–7 start to the season, the Celtics struggled losing ten of their next eleven games, as they traded Andrew DeClercq to the Cleveland Cavaliers for Vitaly Potapenko.  The Celtics finished fifth in the Atlantic Division with a 19–31 record, as fans began to get restless with Rick Pitino's slow growth.  Pierce averaged 16.5 points per game and made the All-Rookie First Team.  Following the season, second-year star Ron Mercer was traded to the Denver Nuggets, and Bruce Bowen signed as a free agent with the Philadelphia 76ers.

Social thriller: A social thriller is a motion picture genre using elements of suspense to augment attention to abuses of power and instances of oppression in society.

Prior to Peele, other film actors, directors and critics had used the term to describe an emerging genre of cinema with examples from all over the globe.

Emo: Emo is a genre of rock music characterized by an emphasis on emotional expression, sometimes through confessional lyrics.  It emerged as a style of post-hardcore from the mid-1980s hardcore punk movement of Washington, D.C., where it was known as emotional hardcore or emocore and pioneered by Washington, D.C. hardcore bands such as Rites of Spring and Embrace.  However, as the genre was taken up by a new generation of musicians in the early 1990s, its sound and meaning shifted and changed and it was reinvented as a style of indie rock and pop punk by bands such as Jawbreaker, Sunny Day Real Estate, Weezer, and Jimmy Eat World.  By the mid-1990s, numerous emo acts such as Braid, The Promise Ring, and the Get Up Kids emerged in the Midwestern and Central United States, and several independent record labels began to specialize in the genre.  Meanwhile, a more aggressive style of emo, screamo, had also emerged, pioneered by the San Diego bands Heroin and Antioch Arrow.

Motswako: Motswako is a Southern African genre of hip hop most popular in Botswana and South Africa.  The genre originated in Botswana in the mid 1990s when a rapper called Mr T (Tebogo Mapine, now popularly known as Nomadic) created a demo of the genre which received rave reviews in radio stations.  It consists of a mix of rap lyrics in both the local language (Setswana) and English layered on a steady beat.  Other languages used include Zulu, French and Afrikaans as per the rapper's origin.  The genre gained popularity in the late nineties as acts like HHP and Baphixile (consisting of "Prof" and "Blax Myth") started rapping in Setswana, resulting in an increased followship from the local population.  Because of its reputation in Botswana most of the upcoming artists use this genre as a base before they start their music careers because of its basic principles, a good motswako artist have to learn the creative writing skills used to perfect the genre making it easy to learn and write music.  Today there is a high pool of motswako artists in Botswana than South Africa with few females artists.

Heist (2008 film): Heist is a one-off 2008 television comedy-drama, written by Peter Harness and directed by Justin Hardy.  It was completed at the end of 2006 and first broadcast on 23 April 2008 on BBC Four as part of its Medieval season.  Loosely based on real events surrounding Richard of Pudlicott, it is a parody of and/or homage to heist films, set in medieval England, using several of that genre's conventions (such as the raid being "one last job", and the use of an unintelligent but physically strong figure), and trailed under the same tagline as the 2003 remake of "The Italian Job" ("Get in, get out, get even").  As per the medieval setting, the film dialogue contains several Middle English and pseudo-Middle English expressions and insults (some of which are translations of modern-English insults or rhyming slang - "mother-swyver" instead of "motherfucker", or "it's all gone a bit church gong" instead of "it's all gone a bit Pete Tong", for example).  Marshall as lead character narrates several parts of the backstory to the audience during the film.

Post-punk: Post-punk (originally called new musick ) is a broad type of rock music that emerged from the punk movement of the 1970s, in which artists departed from the simplicity and traditionalism of punk rock to adopt a variety of avant-garde sensibilities.  Inspired by punk's energy and DIY ethic but determined to break from rock cliches, artists experimented diversely with sources including electronic music, free jazz, and black dance styles like funk, disco, and dub; novel recording and production techniques; and ideas from art and politics, including critical theory, modernist art and literature.  Communities that produced independent record labels, visual art, multimedia performances and fanzines developed around these pioneering musical scenes, which coalesced in cities such as London, New York, Manchester, and San Francisco.

Happy Hero: "Happy Hero" is a single by the experimental band Negativland, appearing on their 1997 album, "Dispepsi".  The song talks about how a man would get publicity by putting himself in danger so he would promote Pepsi on the stage.  The song is sung to a crowd of people, who start booing at him at how he would do such things, like rape with teenage boys and get into a gang fight so he can get into a wheelchair and sing songs to dying children.  The song criticizes Michael Jackson's Pepsi promotion, even though he was accused of raping a 14-year-old boy ten years later.  It's also a foreshadow on "The Greatest Taste Around" as it talks about "dying children", with the lyric in "The Greatest..." saying "children dying of disease/Pepsi".
