look up any word, like tribbing:
Alliterative & hence popular slang term for a tiny fair penis, measuring around an inch erect or flaccid. Based on the small size of the Celtic Penis in particular, & of the British Penis in general: "Irish Inch. sl Lancia in Resta. The erect penis, US 1970s-80s. A slur on Irish penis size. (Green 1998, 642). 'I wanna find what they eat to make their tits grow so I can feed it to my wife.' 'They eat the Irish inch.'(H Gould, Fort Apache 1980, 33)." ('Lessico erotico inglese-italiano' subtitle: La Reggia dell'amore. Antonio D'Eugenio. Bari: Levante, 2002-4, v 1 of 2, p 181) The prevalent stereotype of the microphallic & foolish Celt is a play on the global under-endowed idiot or the Shakespearean 'Three-Inch Fool'.

According to widespread folk & urban legends, British microphallism is a result of a traditional eugenical practise of Norman kings & barons to forbid marriage to British males who measured larger than an 'Irish Inch'. It is said that the aim was to breed an obedient race of under endowed red-haired Celtic & flaxen-haired Anglo-Saxon serfs & that thus originated the 'Curse of the Irish Inch'. Hence the indigenous hatred of the 'Norman Yoke'.

However, this practise would only have exacerbated the evolutionary contraction of heat-losing external body parts (per Allen's Rule) already prevalent in the damp-cold climate of the British Uplands section of the British Insular biogeographic province in the Palaearctic Euro Siberian ecoregion.
