Game: The act of killing an enemy that was weakened by another member of your team. This action will often upset your teammate and should be done with caution. Can also be used as a noun. (kser: kill stealer)
In-depth Version: It's 2 vs 2, you and your teammate and 2 enemies. Both of you have a specific person to kill.

Say your enemy is weakened and you only need more hit on him before you can gain exp/gold/etc.

Your teammate's turn is before yours, and on his turn he kills YOUR enemy. Congradulations! You've just been ksed.

KS is from the Chinese term kong shu (both 1st tones), basically meaning feeling very empty. Absolutely running on fumes.

KS
Abbreviated form of Kinda-sorta. Quick way to say yes to something but at the same time no. Not like IDK which means that you're not sure how you feel, but more like you currently have mixed feelings about it and you can indeed elaborate on it but choose not to.
Dood: So you're a Knicks fan?

Me: KS.

Dood: What do you mean, you like them or not?

Me: Ks...

Dood: YES OR NO???

Me: I DONT KNOW!
