n. 1. (in romance) A person who - by personality, attitude and/or influence - is a true stand-out amongst the norm of dating and relationships. They are generally unaffected by what would be considered
superficial charm (money, appearance,
social status, etc.) and are more attracted to someone's deeper qualities, hence they would "change a player's game." Such persons are considered relationship and even
marriage material.
v. 1. (in sports) A sudden action - usually the result of a successful plan - that changes the entire course of a game or match.
