FS can also mean "full service." In this context, it can be used in various fields to denote a comprehensive or all-inclusive service offering, for example, in hospitality and travel, automotive services, and other professional contexts. However, it is most likely to be found online in adult personal ads, where it is used by sex workers to indicate they provide a comprehensive array of services covering all aspects of their field. For example:

  • "Attractive couple offer FS visits to singles and couples."

For Sale

FS is used in online marketplaces or on social media to indicate that something is available for purchase. For example:
  • FS. Kids' bike. Suitable for 9-12 year old. Good condition.
  • House contents FS. Call for details.

F*ck's Sake

FS can also be an abbreviation of "fuck's sake," which is an expletive phrase used to express shock, frustration, annoyance, or impatience. This usage is very informal and colloquial, and is typically found in texts or online communication where censoring of strong language is desired. For example:

  • "FS! I left the baby in the stroller outside the store!"
  • "FS! Are you going to tell me what's going on or not?"
