Future Fiancé

A term invented in late 2020 that refers to a “boyfriend”, whom you know will propose at some point (hopefully sooner than later). People who use the term #FF are not desperate, rather just on the same page as their significant other.

Person 1- Alyssa is so desperate, she refers to her man as future fiancé!

Person 2- Actually, you just sound jealous! Her FF has already made it clear he wants to get married... therefore “future fiancé” is totally justified in her case!
