Why is the ninth month called September?
North American Indian tribe name, Iroquoian, 1630s, Mohowawogs (plural), said to mean "they eat living things" in a southern New England Algonquian tongue, probably a reference to cannibalism. Cf. Unami Delaware /muhuwe:yck/ "cannibal monsters." The people's name for themselves is kanye'keha:ka. Meaning "haircut style favored by punk rockers" is c.1975, from fancied resemblance to hair style of the Indians in old illustrations. The style of cut earlier was called a Mohican (1960). Mohoc, Mohock, variant form of the word, was the name given 1711 to gangs of aristocratic London ruffians.
A haircut in which the side hair is shaved off, leaving a brushlike line of hair down the middle of the scalp: like this guy that comes into Mattie's all the time with a Mohawk/all make a good Mohawk
[1970s+; fr its fancied resemblance to the hairstyle of Mohawk Indian males; the style was much affected by the punk rockers]
