look up any word, like blumpkin:
an ending exclamation that, at the time, is used to mean "duh" or "why thank you." In most cases, however, the speaker typically has no memory of using this phrase and because of its absurdity, it can insue fits of laughter.
T: It's a movie.
S: I know it's a movie, right franku!
T: What is 'right franku'?
S: What are you talking about? I didn't say that?
T: hahahaha
S: hahahaha
