Croissant

The true presentation of the French boulangerie pâtisseries, showing a masterpiece of flour, butter, eggs, sugar, and an M45 nuclear missile.

"hon hon hon, I eat the baguette and the croissant, hon hon hon ! Jacques hammer !"

Gloubi-boulga

1) the favorite meal of Casimir, a french 70-80's orange dinosaur from a french show called "l'île aux enfants" which translates to "children's island".
2) A french cuisine work of art, made out of Dijon mustard, a Toulouse sausage, one single banana, chocolate flakes and strawberry jam.
3) something absurd in french language.*
4) criticizing a meal in french culture.**

*"ce que tu me dis là, c'est du Gloubi-boulga !" (What you're saying right now is nonsense / absurd !)
**"C'est quoi ce truc ? Tu m'as cuisiné un Gloubi-boulga ?" (What have you cooked, you cooked me a Gloubi-boulga ?)
