Wikipedia
The phrase tally-ho is a largely British phrase, which originated from the activity of foxhunting, and other forms of hunting with hounds, shouted when a rider or follower sees the fox. Today the term has evolved to have other meanings, most of which relate to 'pointing out' or 'spotting' a 'target'. For example, it is sometimes used as slang in air traffic control to verify a radar contact has been visually confirmed.
