Despite French being the language of love, French people do like swearing and are very creative about that. It usually doesn't take much to enrage a French person, they have "le sang chaud" especially in the south of France.
We wouldn't recommend you try it but, in case it happens we would like to teach you some expressions:
1. TU ME FAIS CHIER (YOU ARE SHITTING ME OFF)
2. TU ME GONFLE (I AM GETTING SWOLLEN BY YOU)
3. ET MON CUL, C'EST DU POULET? (IS MY ASS MADE OF CHICKEN?)
4. ON A PAS GARDE LES COCHONS ENSEMBLE (WE DID NOT LOOK AFTER THE PIGS TOGETHER)
5. TU SORS OU J'TE SORS (GET OUT OR I GET YOU OUT)
6. VA VOIR LÀ-BAS SI J'Y SUIS (GO CHECK OVER THERE IF I AM THERE)
7. VA À LA MINE! (GO TO THE MINE)
8. FAUT PAS POUSSER MEME DANS LES ORTIES (DO NOT PUSH NAN INTO STINGING NETTLE)
Swearing in French is much less obscene than in English – which is perhaps more detrimental to French students learning English than vice versa. Translations among swear words are hard to come by since a lot of the meaning depends on the situation and tone of voice.
What is considered vulgar in one language may not be in another. In French, "MERDE" is usually translated as sh*t in English, but it can mean good luck.
