a company with a funny duck who says aflac as a slogan. aflac as an interjection can be used as well when you can't think of something to say, but you know you should talk.
An American LifeInsurance company that has a line of commercials featuring a duck that mysteriously acquires the abnormally-loud voice of Gilbert Godfried. The unnamed duck can only say the name of the Life Insurance company he, for some unexplained reason, endorses: "Aflac." The duck has the ability to appear anywhere in the world where a Life Insurance-related conversation is taking place. However, no human can actually hear his "advice."
(A group of people are chatting)
Dave: Did any of you ever know that I have three testicles?
Rest of group: ............
(Long awkward pause)
You: AFLAC!!!!!!!!!!
