Buzzword bingo! That's where an ignorant person tries to waffle their way through a meeting or interview by using as many buzzwords as possible, usually without knowing what any of them mean.
The bingo part comes from the knowledgeable people who have to endure that stuff - each person comes up with a list of three buzzwords that they expect to hear. The first person to hear all three of their buzzwords uttered by the interviewee calls "Bingo!".
