Killer Nigger 

A Black person who'd be triggered in the smallest nature of provocation, and act in the most ill suited manner as his retribution, which would be way above or supersede the level of initial level of instigation. In most cases it ends with one nigger killing another nigger for the smallest thing.

Ex -
Soulja : Maaaaan, yo mama a hoe!!!!!!!!!
Tyrese: Nigga what you say???? (Pulls out a gun and shoots Soulja)
Sharmice : (Standing Nearby) Maaaan Tyrese such a killer nigger. A nigga disrespect his momma, that nigga dead.

Killer Samaritan 

Someone who trying to be helpful, causes more trouble.

He's such a Killer Samaritan, when he came over to finish our basement for free, he accidently broke a waterline. Now it's flooded.
