Tip
.Private information, secret warning. In horse-racing, it means such secret information as may guide the person tipped to make bets advantageously. A “straight tip” comes straight or direct from the owner or trainer of the horse in question. A man will sometimes give the police the “tip,” or hint where a gang of confederates lie concealed, or where law-breakers may be found. Thus, houses of ill-fame and keepers of clandestine gaming houses in league with the police, receive the “tip” when spies are on them or legal danger is abroad.
