Kill game: when one player wins two pots in a row (outright; no chopping), the limits for the game are doubled (though the blinds remain the same) and the player "on the kill pot" posts the new small bet amount blind no matter his position.

So OP got his kill pot from the button. The game is now 6/12, with the same 1/3 (I presume) blinds, and OP posts $6 blind on the button. So, if it's folded to him, he has an easy raise with A2C to steal the blinds, since he'll make it $12 to go.
