Re: Interesting list
I don't think the definition given on that page makes any sense at all in the context of the commentard's statement.
My suspicion (given the recent vintage of the page, and that's it's not an entirely trustworthy source) is that this is an attempt to retrospectively define the word after it's appeared as a corruption of "au fait", in similar vein to other ongoing online (particularly Twitter) corruption of existing English phrases (cf. Dave Gorman's Modern Life is Goodish "catphrase" and others).
