I’m going to the kitchen comin back with a knife
Cuz I’ve had enough this time
She is about to kill him now because he just didn’t learn his lesson. A few lines before she stated
Just one more error
Could be a fatal step
She already hints there that she is close to losing her cool, and this line now reminds him about how she warned him. The Warning itself also gives the impression that she, now that she warned him, can do whatever the hell she wants, it’s his own fault now.
