Kill Snake 

Referring to first and third person shooters, a kill snake is someone who, at the last second as the player you are engaging has low health, comes in and takes the kill away from you, thus giving you the assist. Basically they take credit for the kill that you were working to get.

I had that guy dead to rights and this guy came up from the side and kill snaked me.
