The porn video tag "pute-francaise" is a combination of two words in French. "Pute" means "whore" or "prostitute," and "francaise" means "Frenchwoman" or "French lady." So, the tag refers to a French woman who is engaged in sexual activities or depicted in a pornographic context. This term is often used by non-native speakers or those familiar with this particular combination of words. For native French speakers, they would likely use "prostituée française" instead.
