To kill another player, usually many levels lower than you, usually in one strike, not giving the other person a chance to fight back. Occurs on MMORPG games like Lineage II and World of Warcraft. Also known as PK'ing or Going Red on Lineage II.
Haha, I gotcha back, thats for ganking me outside Dion Castle Town the other week.
The foul probably-bacteria-based product of sweat, rubber, and stagnant air. Found in your average high school wrestling room - the stench rotates - until it reaches you, festers inside your nose and lungs until you quickstep away complaining of the gank. A sickened facial expression normally accompanies the word.
