French Un Gloubi-BoulgaAn unintelligible babbling or incoherent speech.

Originally: from the french TV show called "L'Ile aux enfants" where fictional main character Casimir ate a dish of this very name composed of strawberry Jam, shredded chocolate, cushed bananas, very strong mustard and Toulouse sausages. Nowadays: used to describe when someone says something completely unintelligible Or a dish, a work in progress, a very strange machinery, something you inherently fear going back to work on dreading that it will cause more chaos than the quality of the thing that will eventually be produced out of this process
