Backstab

Backstabbing is to attack (someone) unfairly, especially in an underhand, deceitful manner. In StarCraft, to backstab (to bs) usually means to turn against and attack ally. It is considered as an immoral act and scorned by many StarCraft players.

Logic and Scenarios
There are multiple different typical reasons and situations which lead somebody to backstab. They include situations with no provocation or ones that are seemingly "legit" and justified.

Backstabbing with no provocation
Some of the time, people backstab for no particular reason and to accomplish nothing significant. Perhaps it is the empowerment of a victory, a higher win score (excluded in some cases), or the ability to overcome an opponent. Scenarios include:


 * Backstabbing in a comp stomp game - A person (or people) will backstab once the computer is defeated. Usually the computer is a distraction for the efforts of the intended backstab victim.
 * Unallied victory - A backstabber is in a game with at least 2 other people and keeps allied victory off. By doing this, after the enemy is defeated, it is impossible to determine who has not checked for Allied Victory. The backstabber then decides to backstab other players under the guise that the victim had not allied victory.
