TT’s RPG glossary defines a twink as follows: “A player who exploits loopholes in the rules (but does not break them) to build PCs that are more powerful than average.

I think that’s a pretty serviceable definition, but much as one person’s erotic art is another person’s porn, every GM will draw the line between fine-tuning a character and twinking in a different spot.

Where do you draw the line in your own games? And how much do the game system and the tone of the campaign affect where that line is drawn? Is there, in fact, a hard-and-fast rule for what constitutes twinking?
