Hair

Hair is a protein filament that grows from follicles found in the dermis, or skin. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types and hair care, but hair is also an important biomaterial primarily composed of protein, notably keratin. Attitudes towards hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, gender, or religion.

Overview

The word "hair" usually refers to two distinct structures:

Girls' Generation

Girls' Generation (Hangul: 소녀시대; So Nyeo Si Dae), also known as SNSD, is a South Korean girl group formed by S.M. Entertainment. The group is composed of eight (formerly nine) members: Taeyeon, Sunny, Tiffany, Hyoyeon, Yuri, Sooyoung, Yoona, and Seohyun. Girls' Generation officially debuted on August 5, 2007 with its debut single "Into the New World" and subsequently gained some attention with their self-titled debut album. However, it was not until 2009 that they rose to prominence with the single "Gee", which claimed the top spot on KBS's Music Bank for a record-breaking nine consecutive weeks and was named the most popular song of the 2000s decade by Melon. The group solidified their place in the South Korean music industry with follow-up singles "Tell Me Your Wish (Genie)", "Oh!", and "Run Devil Run" from late 2009 to early 2010.

In mid-2010, the group signed with Nayutawave Records (present-day EMI Records Japan) to embark into the Japanese music scene. In April 2011, Girls' Generation's Japanese self-titled debut album was released, which peaked atop the Japanese Oricon Albums Chart and became the first album by a South Korean girl group to achieve a double Platinum certification by the RIAJ. The group returned to the South Korean music scene in October 2011 with The Boys, which has sold over 457,000 copies in South Korea, becoming the best-selling album in the Gaon chart history since its launch in 2010. During this time, the group also expanded their endeavor to the United States by signing with Interscope Records. In 2013, Girls' Generation's fourth Korean studio album titled I Got a Boy was released. The title track was subjected to major attention from western media after it was awarded Video of the Year at the inaugural YouTube Music Awards.

YouTube

YouTube is a video-sharing website headquartered in San Bruno, California, United States. The service was created by three former PayPal employees in February 2005. In November 2006, it was bought by Google for US$1.65 billion. YouTube now operates as one of Google's subsidiaries. The site allows users to upload, view, rate, share and comment on videos, and it makes use of WebM, H.264/MPEG-4 AVC, and Adobe Flash Video technology to display a wide variety of user-generated and corporate media video. Available content includes video clips, TV clips, music videos, movie trailers and other content such as video blogging, short original videos, and educational videos.

Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program. Unregistered users can watch videos, and registered users can upload videos to their channels. Videos considered to contain potentially offensive content are available only to registered users affirming themselves to be at least 18 years old.

Classical music

Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a similar term is also used to refer to the period from 1750-1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period. The major time divisions of classical music are as follows: the early music period, which includes the Medieval (500–1400) and the Renaissance (1400–1600) eras; the Common practice period, which includes the Baroque (1600–1750), Classical (1750–1820), and Romantic eras (1804–1910); and the 20th century (1901–2000) which includes the modern (1890–1930) that overlaps from the late 19th-century, the high modern (mid 20th-century), and contemporary or postmodern (1975–2015) eras.

Fuck

Fuck is an obscene English language word, which refers to the act of sexual intercourse and is also commonly used as an intensifier or to denote disdain. Its origin is obscure but is usually considered to be first attested to around 1475, although it may be considerably older. In modern usage, the term fuck and its derivatives (such as fucker and fucking) can be used as a noun, a verb, an adjective, an interjection, or an adverb. There are many common phrases that employ the word, as well as compounds that incorporate it, such as motherfucker and fuckwit.
