Instigator 

Someone who outdoors a kiss ass at what a kiss ass is known for, to the point it isn't called kissing ass with an instigator, its called pleasing or even claims of slavery by the instigator against the other person.

The one major difference between a kiss ass and an instigator is a kiss ass doesn't claim to be anybody's slave, despite doing things just as dehumanizing for other people. An instigator always says they do what they're doing to please other people, but thinks other people are the kiss asses, when really its all similar behavior.
