QFF 

Quoted For Fail - typically used in forums, included after quoting another person, to indicate they were mistaken, suffer from dumacity, or some combination of the two.

"Write for a large audience. Lots of people will read this, so give some background information.
Don't name your friends. We'll reject inside jokes and definitions naming non-celebrities."

QFF - Used more often then the now cliche QFT, previously used by the dusty veterans brigade of forum trolls, QFF is typically not included after a quote, instead being replaced by some form of bipolar, incomprehensible troll rant. Sometimes trolls get lazy, so you just get a "QFF"

Quoted for future reference. Usually used so that even if the original poster deleted their post, the quote will remain as future reference, usually to be used against the original poster if they suddenly change their standpoint.
