A term used in most MMORPGs (Massively Multiplayer Online Role-Playing Games) but specifically WoW (World of Warcraft).
It is when you make a new character and give it advanced weapons, armor, or other equipment. This equipment is usually too advanced to achieve otherwise at such an early level. The player might also give his Twink lots of money to buy equipment, instead.
Many people get angry when they see twinks because they are so much better than them, although they are near the same level. However, in WoW, most weapons have a level you need to achieve in order to use it (i.e. level 10) which limits twinking from getting to extreme.
Verb- (to) Twink
Wow, that level 10 Paladin has a sword that does 30 dps...TWINK ALERT!
Yeah I am going to twink my new character so I can level really fast...
I hate it when you duel those twinkish players and always get owned...GRRRRRR!!!!
