What is "bonne, St.Jeans"?

Question

I'm american, so je ne parle francais. I saw a friend write that as an away message and then she put a lot of beer mugs next to it and I saw it my bus's display screen on my way home.

What is it?

Answer 1

St. Jean-Baptiste Day, June 24th. John the Baptist is the patron saint of Quebec so June 24th has become Quebec's "national holiday". People usually celebrate by getting drunk (and having parades featuring cute young boys, and fireworks).

"Bonne" means good, feminine gender (fête is the missing feminine noun here). The "s" must be a testament to your friend's unabated anglicism. Good on her.
