Attested since the 1300s,^[1][2][3] as Middle English bom^[1] (found in John Trevisa's 1387 Translation of the 'Polychronicon' of Ranulph Higden, "his bom is oute"), of uncertain origin.^[1] Sometimes suggested to be a shortening of botme, botom, bottum (“bottom”), but this is contradicted by the fact that bottom is not attested in reference to the buttocks until the late 1700s.^[4][5] Suggested by some old^[4] and modern references to be onomatopoeic.^[3]

Compare also Old Irish, Scottish Gaelic bun (“base, bottom”).

• Bum is most common in the UK, Ireland, Australia, and New Zealand. In Canada, bum is mainly used when speaking to young children, as in Everyone please sit on your bum and we’ll read a story. In the United States, bum is not often used in this sense (though this may vary from dialect to dialect) except in conscious imitation of British English. The term butt is the most common term in North America except in professional contexts such as medical, legal, and scientific where buttocks is generally used or gluteus maximus, gluteus medius, etc. for the muscles specifically. Glutes is often used in sports medicine and bodybuilding. Ass (originally a dialectal variant of arse) is considered vulgar in North America, whereas backside, behind, bottom and rear are considered to be non-specific terms.
