FTSOF 

For the sake of fuck.

FFS = "for fuck's sake", NOT "for fuck sake".

And, "for fuck's sake" = "for the sake of fuck". Just as "for Pete's sake" = "for the sake of Pete", or "for goodness' sake" = "for the sake of goodness".

Stop typing "for fuck sake", FTSOF!

FTSMF

"Fuck that shit motherfucker"; or, "Forget that stuff, my friend" in case your pastor overhears you. A strong expression of disagreement or rejection.

You: Hey man, instead of having that threesome with your girls tonight, hang out with me while I go to the Department of Motor Vehicles.

Me: FTSMF

FTOF

Fuck The Old Firm.

The "Old Firm" are two scoccer teams that unfortunatley dominate Glasgow football (soccer), and the Scottish Premier League; Glasgow Celtic and Rangers FC. They have a history of extreme Catholic/Protestant sectarianism, which is still present amongst a section of their supporters today. Many of these supporters are neds. More enlightened glaswegians support Partick Thistle FC. Most civilised people will take the attitude of "FTOF".

"Are you watching the match tonight Tam?"

"Nah, Boab, you must be joking - it's the huns... FTOF!"
