[cf. Ir. buide, yellow; grateful].
In the Táin Bó Cuailnge [Cattle Raid of Cooley], Buide is driving Donn Cuailnge [the Brown Bull of Cuailnge] when it first appears in the text. Cúchulainn kills him, but the bull is driven off. Buide is the son of Bán Blai (also Benblai). In some texts Buide is called Buic [Ir., fool, half-wit].
