DF

An endearing acronym used by a person when referring to his or her fiance.

DF stands for "dominance factor," which is a score that some League of Legends (LoL) players use to evaluate their in-game performance. Players with a large number of kills and/or assists and a small number of deaths have a higher DF (and likely really helped their team), while those with a large number of deaths have a lower DF (meaning they let their team down).

At the end of each match, LoL shows players their numbers of kills, deaths, and assists. Players can then calculate their DF by plugging those stats into the following formula:

(2 x Kills) + Assists - (3 x Deaths) = DF

For example, a player with 10 kills, 3 deaths, and 1 assist (or 10/3/1) would have a DF of 12:

(2 x 10) + 1 - (3 x 3) = 12

On the other hand, a player with 2 kills, 5 deaths, and 0 assists (or 2/5/0) would have a DF of -11:

(2 x 2) + 0 - (3 x 5) = -11

DF is an alternative to LoL's Kills Deaths Assists (KDA) ratio, which is a more commonly used measure of in-game performance. Notably, DF seeks to assign players more credit for kills and more blame for deaths, while also accounting for support champs' typically high assist counts.
