FSF

Abbreviation for Full Send Friday, defined as a term used by teenage boys to ask girls to hang out. When receiving a text saying "fsf?", you know you've found a full send type of group who WILL NOT let you down! Make sure you do not interpret it as "Female Seeking Female" as this is a common mistake made by young ladies. PS this term does not only apply to Fridays.

Harrison: "Hey girls, when's the fsf?"
Ladies: "Tonight dude! Get the ronas ready!"
