French Gsce joke

Hi, in my french Excell exam i was writing about what i was going to do with my friend. I said , we are going to go to spain, its going to be fun, i love my friend and all the good stuff. However after i said “there is only one problem, he smells like liquid poop, and hopefully people treat him the same as he is a wonderful person. (I wrote this all in french). Do you know if there are any sanctions or if its not offensive enough to get sanctions? I know its childish but i’ve been writing that joke since year 10 and it was fine, the teacher liked it.
