Fabien
A Fabien is a guy who’s kind but also a little nuts. He’ll be your best friend one minute and then try to feed you a whole pizza the next.
My Fabien brother tried to pet a dog and the dog bit him.
My Fabien friend said he was going to be a chef and then ate a whole cake in one go.
My Fabien classmate told me he was going to be a superhero and then ran out of the room like he was being chased.
