In describing the customs of the Mayas inhabiting the Verapaz province (including the Alta Verapaz and Baja Verapaz) of 16th-century Guatemala, Bishop Bartolomé de las Casas mentions sexual relationships, regulated by customary law, between unmarried young men and boys, as well as similar relations prevailing among adolescents receiving instruction in the temples. Chin, together with Cu, Cavil ('idol'), and Maran, is mentioned as the name of the male deity said to have demonstrated homosexual intercourse with another 'demon', and thereby to have introduced such relationships: "From that time on some fathers gave their sons a little boy to be used as a woman; and if someone else took the boy, they demanded pay as is done when someone violates another's wife." Institutionalized pederastic prostitution, including transvestism, is recorded in 17th-century Spanish reports of the Itzá Mayas living in the Petén. Among the Classic Period scenes found in a cave of Naj Tunich is a depiction of a naked, sexually excited male creature embracing a nude Maya nobleman, possibly by way of initiation.

The chin or the mental region is the area of the face below the lower lip and including the mandibular prominence. It is formed by the lower front of the mandible. In humans there is a wide variety of chin structures, e.g. cleft chin.

In human evolution, the chin is a cladistic apomorphy, partially defining anatomically modern humans as distinct from archaic forms. Non-human anthropoid apes have a simian shelf for example. Elephants are the only other animals considered to display such a feature, although this leads to debate over the use of the term.

The chin emerged during the Middle and Late Pleistocene, but its origin and biomechanical significance are the subjects of controversy. Prominent hypotheses include buttressing the jaw against stresses resulting from speech or chewing as well as simple sexual selection through mate choice. With the advent of more advanced computational facilities, finite element analyses have been used to support hypotheses involving mechanical stress. On the other hand, increased availability of data regarding sexual dimorphism in chins has also lent support to the sexual selection hypothesis as sexual dimorphism is more difficult to explain under other regimes. It is possible that multiple causal factors have played a role in the chin's evolution.

In combat sports such as boxing, kickboxing and mixed martial arts, a fighter's chin is a figurative term that refers to an ability to tolerate physical trauma to the head without being knocked unconscious. The fictional Rocky Balboa character of the Rocky franchise epitomizes the concept of a boxer with a granite chin.

CHIN is a Canadian radio station, which broadcasts multilingual programming at AM 1540 in Toronto, Ontario. It is a Class B station broadcasting on a clear-channel shared by The U.S. and The Bahamas. It is owned by CHIN Radio/TV International, and also has an FM rebroadcaster at 91.9 to fill in reception gaps in parts of the Toronto area — this should not be confused with CHIN-FM, which offers a distinct program schedule. CHIN's studios are located on College Street in the Palmerston-Little Italy neighbourhood of Toronto, while its AM transmitters are located on Lakeshore Avenue on the Toronto Islands, and the FM rebroadcaster is located atop an apartment tower complex near Bathurst and Sheppard in Toronto's Clanton Park neighbourhood.

The station, one of Canada's first multilingual broadcast outlets along with Montreal's CFMB, was launched in 1966 by Toronto broadcaster Johnny Lombardi. CHIN-FM was launched the following year, and a second FM signal acting as the AM station's FM rebroadcaster was added in 1997 (at 101.3 MHz) with the call letters CHIN-1-FM.

On April 17, 2003, Radio 1540 Ltd. was given approval to change the frequency of CHIN-1-FM Toronto from 101.3 MHz to 91.9 MHz and to increase the effective radiated power from 22 to 35 watts.

CHIN's daytime lineup consists primarily of Chinese ( Cantonese & Mandarin) and Italian programming, with some Albanian, Bengali, Bosnian, Bulgarian, Croatian, German, Greek, Irish, Jewish, Romanian, Somali, Spanish and Ukrainian programming airing on Saturdays & Sundays.

On January 14, 2011, CHIN received approval to increase the effective radiated power for the CHIN-FM-1 91.9 FM transmitter from 161 to 1,850 watts (maximum ERP from 350 to 5,000 watts with an antenna height above average terrain of 86 metres).

On February 10, 2016, CHIN dropped the simulcast of China Radio International in the evening and overnight hours and replaced it with dance music-formatted programming originating from internet broadcaster "DJFM Toronto."
