twink

In tabletop or online RP settings, a twink (often also referred to as a munchkin) is someone who has min-maxed their character to emphasize a single set of game stats rather than creating a well-rounded character. While these characters are most often geared toward combat, there are a variety of twinks, often differentiated by an accompanying title, such as combat twink, TS twink/sex twink, social twink, gear twink, or others. This seems the most likely origin for the MMORPG version of the term, since tabletop and online RPGs were the precursors to games like World of Warcraft, and the definitions share similarities.
