What is "fè sirèt"?

Mezanmi o!

"fè sirèt" is a mishap that many Creole speakers experience when speaking French.  They swap the French "u" for "i", and the "i" for "u".

It sounds awful. It is funny and embarrassing especially for an "intellectual" who's speaking French in a public/social setting.

If this happens while speaking Creole, it's no biggie.  

But some Haitians will never forgive you for scorching their ears like that.  Some will even make fun of you.

Students have been merciless to teachers trying to teach a class in French when they can't even handle their French.
