The right for a team to bat in the last (bottom) half-inning of a baseball
game, because the other team batted in the first (top) half-inning to start the game, so that each team gets an equal number of turns at bat.
In an organized game, the home team gets last licks. In informal games, players may forget which team batted first, so near the ending time of a game, a player whose team is behind in the score may call out to remind other players that his team has last licks.
You guys batted first, so we have last licks.
