Poker Acronyms - FFS
FFS= "For f*cks sake"
Usually used when at an online poker table - and particularly common at loose, low and micro-level tables. Tends to be exclaimed when a player suffers a "bad beat" - an unlucky flop, turn or river - but can also get typed when an opponent turns over either very good or very bad cards - for example if player1 is all in with KK and his/her opponent turns over aces, that tends to generate a "ffs" response.
Player least likely to type FFS : Irish Pro "Gentleman" Liam Flood.
