Wikipedia
Twinking is a type of behavior in role-playing games. A player who engages in such behavior is known as a twink. The precise definition of twinking varies depending on the variety of role-playing game. In "pen and paper" role-playing games, a twink is often synonymous with a munchkin. In MUDs, a twink is a player who is variously anything from a munchkin to a newbie to a griefer. In MMORPGs, twinking refers to a character gaining equipment with the assistance of a higher level character, particularly by giving said low level character higher level equipment that is otherwise unattainable, or the process of keeping a video game character at a low level while using in-game currency, earned by a high level character, to provide it with superior equipment.
