Here is a quick example of "expressions" as i meant it. I went on there and typed
"la marine pa métyé ou". Google translate's interpretation say
"The marine trades by you" 
In reality "la marine pa métyé ou" is an expression that means the same thing as when you americans say
"don't quit your day job".

.
If you translated it word for word correctly it would say "Being a sailor is not your profession" but still wouldn't get the point across. So you can imagine how hard i be laughing when my yankee or other non kreyol speaking friends try to use google translate to talk shyt to me in kreyol. Them shyts be like extreme comedy to me when she would do that sh!t thinking google translate gonna teach her kreyol
