An acronym for "For fuck's sake", meaning "I can't believe this shit, I demand you to stop"

The source is For Christ's sake ("in Christ's name please explain/stop that"). Swap in Fuck All ("nothing") for the deity, and you get an urban, angry, non-religious, expletive, demanding equivalent of "Oh My God, do something".

2. FFS, I've explained it to you five times already. Now STFU!

1) For Fuck's Sake - a common expletive used online.

2) Flying Farang Syndrome - when rich older western men move to Thailand, marry a young Thai girl and can 'suddenly' realise they can fly from a high rise condominium on their honeymoon. As a result this leads to the death of the foreigner (farang in Thai) and a quick inheritance for the 'grieving' bride.
