Derived from 'QFT,' which is an abbreviation of the phrase 'Quoted For Truth.' Commonly used on message boards to emphasize a point previously made, when the person quoting the point has nothing more to add.
Variation of the acronym QFT (Quoted for Truth), replacing the word 'for' with the numeral four. Used mainly on internet forums.
