What does FBS stand for?

Answer 1

In a Hobby sense, I find no acronym that really applies...

Fédération Belge de Scrabble (that fits games)??

There is an FBS Cars in the UK: http://www.fbscars.co.uk/

If computers are your hobby, Flexible Bandwidth Service might make sense...

Here are the others I could find:

Fetal Bovine Serum
Fatboy Slim (band)
Federal Bureau of Statistics (Pakistan)
Fasting Blood Sugar
Football Bowl Subdivision
Funktionsbausteinsprache (German: Function Block Diagram)
Fidelity Brokerage Services
Fetal Blood Sample
Fixed-Base Simulator
Foreign Body Sensation
Frequency Based Scheduler
Fanconi-Bickel Syndrome
