I had been seeing “ftw” in internet chit chat for a while, and I just finally got around to looking it up and seeing what it actually means: “for the win”.

In the meantime, I had just sort of assumed it was an inversion of “wtf” — sort of taking the aghastness of “wtf” and adding onto it a fillip of “wack”! So I’d been reading it as “fuck the what!”. I actually like that a lot better than “for the win”.
