So, some one have asked how this "french" thing came... I hadn't much time to write about it.
I guess you know about French Revolution (Pransha Viplavaya). Before then, France had the victorian culture and politics.
After the French revolution, other countries, specially England teased French people as the "ones who killed their own king"!
France went against the Victorian system, taking a radical socialist system. French literature, art and music developed rapidly.
Among othher Europian countries France was outstanding in easthetics in a "Modern" way.
The Modernism (which lead to the present Post Modernism - Pashchath Nuuthanavaadaya) began in France after the French revolution.
In Europe, all the odd things, and all the Modern, Radical, Romantic things were called as French.
So came the French Fries, French Kiss, French Leave.., etc.
