bravo vince
Bravo Vince is in reference to Vince Gilligan, one of the producers and writers for The X-Files and creator of Breaking Bad and Better Call Saul. He's widely considered a modern day auteur of television. Bravo Vince can be used sincerely as a complement, but is more commonly used sarcastically in response to a false or exaggerated behind-the-scenes claim - usually predicated by "fun fact" or "little known fact" - making light of the lengths the shows' crews would be known go to for quality.
Person A: Little known fact, when one of the cousins needed to be an amputee, Vince Gilligan himself sawed the actor's legs off personally. He was screaming the entire time, but when it comes to authenticity and craftsmanship, Vince Gilligan takes no prisoners.
Person B: Wow, that's impressive! Bravo Vince!
