Tally-ho is an expression shouted out by hunters to signal a successful hunt or to rally the hunting party. The phrase has its roots in the 18th century, where it was used exclusively by foxhunters in England. Synonyms for this phrase include "view-halloo," "Haloo," and "hoicks." They all have similar meanings and were used to alert the hunting party in the same way. Other synonyms for tally-ho that can be used in different contexts include "Charge!" "Attack!" and "Go get'em!" These words are typically used to motivate or encourage people to take action, similar to how tally-ho is used in a hunting context.
