The danger,
The one who knocks.
SKYLER WHITE
Walt, please, let's both of us stop trying to justify this whole thing and admit you're in danger!

WALTER WHITE

Who are you talking to right now? Who is it you think you see? Do you know how much I make a year? I mean, even if I told you, you wouldn't believe it. Do you know what would happen if I suddenly decided to stop going into work? A business big enough that it could be listed on the NASDAQ goes belly up. Disappears! It ceases to exist without me. No, you clearly don't know who you're talking to, so let me clue you in. I am not in danger, Skyler. I AM the danger! A guy opens his door and gets shot and you think that of me? No. I am the one who knocks!

Used in terms of the famous character from Breaking Bad. Walter White went from a protagonist to the antagonist, simplified, he went from a submissive and weak man to an almost unstoppable killing machine and drug lord. This term can be when you or someone else goes from quite or shy to over confident or outrageous.
1: Hey did you see Anon in class today?
2: Yeah they went all Walter White on that bitch pushing them around

Rhyming slang for 'Shite'.

A particularly pungent poo that smells so bad it makes you cough like Heisenberg.
"The cat has done a Walter White in the kitchen that smells so bad I nearly coughed up blood."
