Billy
n.— «“So I said to him, “Fine, but just before you’re going into one of them can you give me the Billy?” That’s Dublin slang for give me the nod. “So he says, ‘Yeah great no problem.’ So the song is coming to an end and Van starts to shouting, ‘Billy! Billy! Billy!’”» —“Morrison Fails To Pick Up On Irish Slang” Contactmusic (U.K.) July 27, 2005. (source: Double-Tongued Dictionary)
