Vince Gilligan was a writer of Breaking Bad and Better Call Saul, and people said, "Bravo, Vince!" when there was a small detail in one of the two shows. People have said it so much that it has become a meme, and people now say it when there is a detail that is most likely unintentional. Some people switched this to, "Vravo, Bince!" as a joke.
Person 1: Such a subtle detail in Breaking Bad when it started with capitalism (healthcare), and ended with capitalism! (the Popcorners commercial)
