Origin
From Middle English bole, bul, bule, from a conflation of Old English bula (“bull, steer”) and Old Norse boli, both from Proto-Germanic *bulô (“bull”), from Proto-Indo-European *bʰl̥no-, from *bʰel- (“to blow, swell up”). Cognate with West Frisian bolle, Dutch bul, German Low German Bull, German Bulle, Swedish bulla; also Old Irish ball (“limb”), Latin follis (“bellows, leather bag”), Albanian bolle (“testicles”), Ancient Greek φαλλός (phallós, “penis”). Of sense 11, (a man or boy), derived from the Philadelphia English pronunciation of boy, which is practically a homophone of bull.
