• plural noun the buttocks. A popular term since the early 1970s which is not particularly vulgar and which is gaining currency outside North America. The origin may be an obsolete northern British dialect term for ‘tail’, a variation on bum, or may simply refer to the parallels in form and texture with edible buns.
  • plural noun sanitary towels or tampons. A shortening of ‘jam buns’ used almost exclusively by men. (‘To have the buns on’ is to be menstruating.).
