Yep! The first time I went to France, I was amazed at how all the little French kids knew how to speak it, but I was still struggling after 3 years of French in high school. /s
You master French and then you find out the French have this funny habit of reversing the syllables of their words (Verlan)...
Tromé (Métro – Metro) ...
Cimer (Merci – Thank You) ...
Ouf (Fou – Crazy) ...
Oim (Moi – Me) ...
Meuf (Femme – Woman) ...
Reuf (Frère – Brother) ...
Reum (Mère – Mother)
