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.

Terminoligy spawned by Michael Altenburg (aka Axlrose7000) at the Minibosses message board. Used in lieu of LOL, it stands for "knee slapper" and is to be deployed in times of hilarity.

Kill Steal, these two words is create for other games, some players have been misuse them and result Maple Story Team think there is an action call KIll Stealing in Maple Story

Example, in DarkAges, our party is hitting a monster, a warrior appear and use a warrior skill call rescue on the monster, and kill it, Full experience goes to the warrior that give the final hit (Kill Stealing Happen)

Example, in CounterStrike, I shooting an enemy for a period of time, and when the enemy is dying, my teammate jump out and kill him (Kill Stealing Happen)

Example, in Gunbound, Game Start, I and my teammate start damaging the enemy nearby, then when my enemy(target) is dying, my teammate change his target and kill my target (Kill Stealing Happen)

Example, in Shattered Galaxy, Battle start... using a group of apparition walking around the map, saw a group of Arbalest, and i start shooting them, then my teammate control his eagle(which currently attacking another enemy) fly toward us and kill the Arbalest (Kill Stealing does not happen, because we should help each other in battle and if we win the battle, I still get experience for the battle)

Example, in Maple Story, training in SleepyWood Dungeon, kill a monster that previously damaged by another party(Kill Stealing does not happen, because he still recieve the experience for damaging the monster)

Example, in Prince of Qin, training in a forest, kill a monster that previously damaged by another party (Kill Stealing does not happen, because he still recieve the experience for damaging the monster)
