the appreciative reaction one may feel when being exposed to something overly french. this may be an emotional and/or physical response.
This afternoon I was taken to a nice little café hidden in a narrow cobbled alley, there we tasted wine and cheese to the sound of some accordion. It totally gave me a frenchgasm.
Would you look at this little girl with a beret, it's such a cutegasm except french ... Frenchgasm!
