Keyslayer 

In world of warcraft when inviting members to your group, a keyslayer is a player who notoriously causes problems that prevent you from timing the key or completing it all together.
See Nickheals.

This key was going so well until the keyslayer started dying repeatedly causing us to not time it.

Keysaber 

A modified version of the Keyblade seen in the fanfic DDR HEARTS (by Darkness Shade). The weilder of it is Ryan, an unofficial jedi, whose saber was combined with the keyblade just before he was transported to Traverse Town.

"Well, what you have is the Keyblade, but it combined with your saber and became the Keysaber. It is the one thing that can stop the Heartless." - Leon

At that moment my saber, changed. It became the shape of one of those old style key's with the top
part the handle and the rest the light beam. "Wow, that's new." - Ryan
