"Cest la vie" is a French phrase that means, roughly, "that's life." It did not become popular.
"Bahala na", a phrase from the Philippines, which I can't remember who I gave to first, is making the rounds among the villagers. Have no clue why, but it means, again roughly, "what will be, will be" or "God willing."
"Mabuhay" is another Philippine word that means "live." A few villagers use it.
I have lots more, because I like to have fun with them. I get a request just about every day, but that's all for now!
Forgot to say I like all the great new ideas in this post! Thanks!
