A meme originated from a scene in Breaking Bad. The original scene involves Walter White yelling at his brother-in-law Hank Schrader to warn him about the men that were sent to kill him.
Parodies of this scene first originated from 4chan post parodying a scene in Breaking Bad where Walter White yells from a car window at Hank to get sweet and sour sauce, not barbeque. It later spawning a meme format in which Walt tries to warn Hank of various things.
