Someone or something that gains benefit by being around you at opportune moments without your consent. Such as the little fish that follow sharks, or a bird that lands on Oxen to eat bugs off them
When your playing dominoes and you score a 20 and the next person in-turn lays down a blank/5 domino and scores a 25, you can call him an ox pecker.
