ballyhoo (n.) Look up ballyhoo at Dictionary.com
"publicity, hype," 1908, from circus slang, "a short sample of a sideshow" used to lure customers (1901), which is of unknown origin. There is a village of Ballyhooly in County Cork, Ireland, (the Bally- is a common Irish place-name element meaning "a town, village") but no evident sense connection. In nautical lingo, ballahou or ballahoo (1867, perhaps 1836) was a sailor's contemptuous word for any vessel they disliked (from Spanish balahu "schooner"). As a verb from 1901 (implied in ballyhooer).
