What is a bientot?

The phrase "à bientôt" is French and translates to "see you soon" in English. It is a common expression used in French-speaking regions to bid farewell to someone when you expect to see them again relatively soon. It's considered polite and friendly, often used among friends, acquaintances, or in professional settings when the parties anticipate meeting again in the near future.

If you were referring to something other than the French phrase, please provide more context, and I'll be happy to help with that.
