The Jug Factor (or TJF) is an important theory when it comes to calculating the number of votes a character is likely to receive in a Summer Contest. TJF takes two main elements into consideration: 1. Is the character female? 2. If yes, how large are her breasts? Believed to be a contributing factor to the success of Lara Croft, and in Tina Armstrong's defeat of Gordon Freeman. It is unknown whether the latter is the origin of, or simply a result of, GFNW.
